Limit Switches
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.
Switches with a plunger actuator require a push to actuate, similar to a button.
Switches with a roller plunger or cross roller plunger actuator have a roller that moves when an object pushes the actuator. This reduces friction during actuation to limit wear and tear on your switch.
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.
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.
Switches with a 4-pole micro M12 plug connect to cables with a socket (sold separately), allowing you to quickly connect and disconnect the switch.
Styles E and F let you adjust the actuator’s height to align it with your target.
Switches rated IP67 are protected against dust and temporary submersion.

Rotary Limit Switches
Start or stop equipment after a set number of rotations to avoid over-rotation. For example, if attached to a crane spool, these switches will stop winding or unwinding cable after a certain number of rotations, preventing damage to equipment. Use their shaft to attach them to rotational equipment. They open and close circuits as fast as snap-acting switches.
Gear speed ratio determines when these switches actuate. A gear speed ratio of 5:1 means they actuate after 5 rotations.

Safety Limit Switches
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.
Switches with a plunger actuator require a push to actuate, similar to a button.
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.
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.
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 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.
Switches with a steel actuator are more durable than switches with a plastic actuator. They also handle higher loads.
Switches with a plastic actuator limit wear and tear on passing objects better than switches with a steel actuator.

Compact Safety Limit Switches
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.
Switches with a plunger actuator require a push to activate, similar to a button.
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.
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.
Switches with a rod actuator have a large actuation area with a rod extending out of the actuator’s body. They’re best where the object actuating the switch is far away.
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.
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 and IP67 rated switches are protected from oil/coolant spraying and temporary submersion.

Washdown Limit Switches
Rated NEMA 3S and IP69K, these switches can handle washdowns with high pressures and temperatures. They’re also protected from oil/coolant spraying, precipitation, and temporary submersion. When an object in motion contacts 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.
Switches with a plunger actuator require a push to actuate, similar to a button.
Switches with a roller plunger actuator trigger just like a plunger actuator but reduce friction during actuation thanks to their roller. This limits wear and tear on the switch.
Switches with a roller lever actuator combine the larger actuation area of a standard lever with a smooth gliding roller actuator. They minimize friction to limit wear and tear on your switch.
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.
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 D, E, and F let you adjust the actuator’s height to align it with your target.

Frame-Mounted Safety Switches
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.
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. Flexible keys pivot at least 15°, making them easier to align with switches during installation.
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 rated switches protect against temporary submersion.
