M12 Connection |
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 Plunger Actuator—Switches with a 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.
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.
4-Pole M12 Connection—Switches with a 4-pole M12 plug connect to cords with a socket (sold separately), allowing you to quickly connect and disconnect the switch.
Style E—Styles E and F let you adjust the actuator’s height to align it with your target.
IP67 Enclosure Rating—Switches rated IP67 are protected against dust and temporary submersion.

Sealed Low-Profile Limit Switches
 |  |  |
Style B | Style C | Style D |
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.
Roller Plunger Actuator—Switches with a 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.
Cross Roller Plunger Actuator—Switches with a 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. The roller moves perpendicular to the mounting direction.
4-Pole M12 Connection—Switches with a 4-pole M12 plug connect to cords with a socket (sold separately), allowing you to quickly connect and disconnect the switch.

Frame-Mounted Safety Switches
 |
Key Shown Actuating from the Side |
 |  |
Style F | 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 F—Style A-G switches have positive-force, normally closed contacts that will open a circuit when the switch is actuated even if a spring fails or the contacts stick.
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.
