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 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.
