When a moving object contacts the actuator on these switches, they open or close a circuit. They have the rapid-closing action of a snap-acting switch, but with a larger actuator. This makes them a good choice for use with large objects—for instance, a box on a conveyor runs into the switch, stopping the conveyor.
Plunger Actuator—Switches with a plunger actuator require a push to actuate, similar to a button.
Roller Lever Actuator—Switches with a roller lever actuator use a lever with a roller at the end to activate. This allows parts to glide across the actuation surface with minimal friction, limiting wear and tear on your switch.
Rod Actuator—Switches with a rod actuator use a rod extending out of the body to actuate, so they’ll activate even if an object is far away.
T-Rod Actuator—Switches with a T-rod actuator have four rods extending in different directions from a pivot point. If an object contacts any of the rods from any direction, these switches actuate. Since they have such a large actuation area, they’re great for detecting moving parts when your machine tool isn’t perfectly aligned.
Wobble Stick Actuator—Switches with a wobble stick actuator have an arm that rotates 360°, so you don’t need to align it in a specific direction. Since the actuator is flexible, it won’t snap if pushed backward. That makes these switches a great choice for systems that get jammed often.
Styles E and F—Styles E and F let you adjust the actuator’s height to align it with your target.
NEMA 13 Enclosure Rating—Switches rated NEMA 13 are protected against dirt and oil/coolant spraying.
IP67 Enclosure Rating—Switches rated IP67 are protected against dust and temporary submersion.

Low-Profile Limit Switches
 |  |  |
Style A | Style C | Style E |
Stack these slim switches together, or fit them into tight spaces. They're rated IP67 for protection from temporary submersion. When an object in motion comes into contact with the actuator, it sends a signal to open or close a circuit. These switches have the rapid-closing action of a snap-acting switch, but have a larger actuator for large objects. They’re often used on conveyor systems and elevators.
Plunger Actuator—Plunger actuators open or close circuits when objects push against them.
Roller Plunger Actuator—Roller plunger actuators open or close circuits when an object pushes against the roller, which moves the plunger. The roller moves parallel to the mounting direction, so it helps push the plunger even if the force isn’t straight on. The roller also reduces friction during actuation which prevents wear and tear over time.
Roller Lever Actuator—Roller lever actuators open or close circuits when material moves across the switch. The roller reduces friction during actuation which prevents wear and tear over time.
Plastic Housing and Powder-Coated Zinc Alloy Housing—Switches with plastic or powder-coated zinc alloy housings are rated NEMA 4 and 13 for protection from washdowns and oil/coolant spraying.

Compact Safety Limit Switches
 |  |  |
Style A | Style B | Style C |
 |  |  |
Style D | Style E | Style G |
Shorter and thinner than other safety limit switches, these are sized to fit tight spaces. They protect machinery and ensure the safety of personnel. Positive-force contacts open the circuit when actuated, even if a spring fails or the contacts stick. They send a signal to your circuit when an object hits the actuator—for instance, a box on a conveyor runs into the switch, stopping the conveyor. They open and close circuits as fast as snap-acting switches, but they have a bigger actuator for large objects. All are NEMA and IP rated for protection from washdowns.
Plunger Actuator—Switches with a plunger actuator require a push to actuate, similar to a button.
Roller Plunger Actuator—Switches with a roller plunger actuator have a roller that moves parallel to the mounting direction when an object pushes the actuator. This reduces friction during actuation to limit wear and tear on your switch.
Roller Lever Actuator—Switches with a roller lever actuator use a lever with a roller at the end to activate. This allows parts to glide across the actuation surface with minimal friction, limiting wear and tear.
Wobble Stick Actuator—Switches with a wobble stick actuator have an arm that rotates 360°, so you don’t need to align it in a specific direction. The actuator won’t snap if pushed backward, such as if there’s a jam in your system.
Style E—Styles E and F have an actuator that allows you to adjust its height, making it easier to align the switch with the target during installation.
NEMA 13 Enclosure Rating and IP67 Enclosure Rating—NEMA 13 and IP67 rated switches are protected from oil/coolant spraying and temporary submersion.

A sealed actuator prevents these switches from jamming, even when exposed to sand, mud, or dirt. They're also rated IP67 for temporary submersion. With a slim design, you can stack them or fit them in tight spaces. When an object in motion comes into contact with the actuator, it sends a signal to open or close a circuit. These switches have the rapid-closing action of a snap-acting switch, but with a larger actuator. This makes them a good choice for use with large objects. For instance, a box on a conveyor runs into the switch, stopping the conveyor.
Plunger Actuator—Switches with a plunger actuator require a push to actuate, similar to a button.
Plastic Housing and Powder-Coated Zinc Alloy Housing—Switches with a powder-coated zinc alloy or plastic housing are rated NEMA 4 and 13 for protection from washdowns and oil/coolant spraying.

Style C | Style F |
Protect machinery and ensure the safety of personnel—these switches have positive-force contacts that will open the circuit when actuated even if a spring fails or the contacts stick. When an object in motion comes into contact with the actuator, it sends a signal to open or close a circuit. These switches have the rapid-closing action of a snap-acting switch, but with a larger actuator. This makes them a good choice for use with large objects—for instance, a box on a conveyor runs into the switch, stopping the conveyor.
Roller Lever Actuator—Switches with a roller lever actuator use a lever with a roller at the end to activate. This allows parts to glide across the actuation surface with minimal friction, limiting wear and tear on your switch.
Rod Actuator—Switches with a rod actuator use a rod extending out of the body to actuate, so they’ll activate even if an object is far away.
Style F—Styles D, E, and F have an actuator that allows you to adjust its height, making it easier to align switch with the target during installation.
Plastic Actuator—Switches with a plastic actuator limit wear and tear on passing objects better than switches with a steel actuator.
Steel Actuator—Switches with a steel actuator are more durable than switches with a plastic actuator. They also handle higher loads.

Manual-Reset Safety Limit Switches
 |  |  |
Style A | Style B | Style C |
Prevent equipment from automatically restarting—these switches must be manually reset each time they're actuated. Pull the knob to reset. Positive-force contacts open the circuit when actuated, even if a spring fails or the contacts stick. These switches send a signal to your circuit when an object hits the actuator—for instance, a box on a conveyor runs into the switch, stopping the conveyor. They open and close circuits as fast as snap-acting switches, but they have a bigger actuator for large objects.
Rated IP67, these switches seal out water if they’re washed down or briefly submersed.
Style B—Style B have a roller lever actuator that allows parts to glide across the actuation surface with minimal friction.
Style C—Style C have a roller lever actuator that allows parts to glide across the actuation surface with minimal friction. You can also adjust the actuator's height, making it easier to align the switch with the target during installation.

Frame-Mounted Safety Switches
 |
Key Shown Actuating from the Side |
 |
Style J |
Also known as interlock switches, these ensure the safety of personnel by automatically shutting off power to machinery when an access door opens. Mount the switch to the door frame and mount a key to the door so that the key is inserted into the switch when the door is closed. When the door opens, the key is removed from the switch and the machine shuts down. They’re often used with machine guards for large robots.
Style J—Style J switches have extra safety controls to prevent you from getting trapped next to running machinery. They actuate with the turn of a portable key. Bring the key when you enter an enclosure to ensure machinery won’t start while you’re inside, even if the door closes behind you. As an added fail-safe, a rear release button lets you cut power from inside of enclosures if needed. These switches have light-up indicators that show when they're properly installed and whether they're actuated.
IP67 Enclosure Rating—IP67 rated switches protect against temporary submersion.
Key Included—All switches require an actuator key, but not all include one—check whether you need to pick out a separate actuator key. For some switch styles, you can also select the mounting orientation of the key.
