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.
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.

Rated IP67, these switches have an enclosure that shields their interior during temporary submersion. They open and close circuits in a snap—their quick actuation limits arcing and keeps contacts from sticking. These switches are often used to indicate an open appliance or enclosure door. You can also use them inside limit, pressure, and temperature switches.
Plunger Actuator—Switches with a plunger actuator require a push to actuate, similar to a button.
Roller Lever Actuator Style—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.
Roller Plunger Actuator—Switches with a roller plunger actuator have a roller that moves parallel to the body length when an object pushes the actuator. This reduces friction to limit wear and tear on your switch.
With 4-Pole Micro M12 Plug—Switches with a 4-pole micro M12 plug quickly connect and disconnect from your switch.
