Install these limit switches where changing a battery or routing wires might be difficult—they power themselves when a moving object contacts the actuator. Place them up to 330 ft. away from the receiver (sold separately). These switches have the rapid-closing action of a snap-acting switch, but with a larger actuator.

Plunger actuators open or close circuits when objects push against them.

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 actuators open or close circuits when material moves across the switch. The roller reduces friction during actuation which prevents wear and tear over time.

Rod actuators open or close circuits when material pushes against the rod. The rod extends from the body of the actuator, so these switches are ideal when objects actuating the switch are further away.

Use an antenna (sold separately) to increase the maximum transmission range to 984 ft. They also strengthen the signal if there are obstacles between your switch and receiver.
