Reversing Motor Switches

With Steel Enclosure

With Plastic Enclosure

Use these switches to control the on/off function of motors that run forward and backward, such as motors for conveyor belts. They can also be used with other circuits such as lighting and electric heat circuits, but do not provide overload protection. Also known as drum switches.

Switches that have maintained/momentary switch action are supplied to stay switched (maintained), but can be wired to spring back (momentary).
