SPDT Vertical Lever Arm Limit Switch

The Dayton SPDT vertical lever arm limit switch provides position sensing for industrial control circuits. Its single-pole double-throw contacts switch 5 A at 240 V AC. A NEMA 13, 3, 4 rated micro body measures 1.27 in high, 2.29 in wide and .71 in deep. Screw terminals allow straightforward wiring for maintenance technicians and panel builders.

Replaces worn micro switches in conveyor stops

The switch suits applications needing a top-mounted roller lever actuator with SPDT action. It is not rated for DC loads, so DC control circuits must use a different device. The boot-sealed actuator is absent, making it unsuitable for environments where dust or moisture ingress protection beyond the NEMA rating is required.

Surface mount with two screws and screw-terminal

Installers secure the micro body to a flat surface and connect wires to the screw terminals. The vertical lever arm must align with the target cam or dog to avoid side loading the plunger. Over-travel beyond the lever's mechanical limit can damage the actuator, so mechanical stops should be set during commissioning.

Questions about this item

What are the body dimensions I need to clear for the 1.27 in high, 2.29 in wide, 0.71 in deep switch?

The switch body measures 1.27 in high, 2.29 in wide and 0.71 in deep; allow that envelope plus the vertical lever arm travel when planning the mounting surface.

How do I wire the SPDT screw terminals and what is the common mistake?

Connect the common, normally open and normally closed wires to the three screw terminals; the frequent error is swapping the normally open and normally closed leads, which reverses the switching logic.

When should I replace the lever arm or the switch body?

Replace the lever arm if the roller shows flat spots or excessive play, and replace the entire switch if the SPDT contacts no longer make reliable 5 A at 240 V AC switching.
