About Motor Switches and Starters

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).

Washdown Reversing Motor Switches

Rated NEMA 4, these switches are protected from washdowns. Use them 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.

Washdown Programmable Three-Phase AC Motor Speed Controls

Rated NEMA 4, these controls are protected from washdowns. Set them to automatically adjust motor speed. Wire a potentiometer (not included) for remote manual control.

Controls rated NEMA 12 also protect against splashes of oil and coolant when used indoors.

Three-Phase AC Motor Speed Controls

Vary the speed of three-phase AC motors. Mount these controls inside a machine or control cabinet. They’re often used in packaging machines, conveyors, and vacuum equipment. Operate controls manually or remotely with an electrical signal.

Input adapters (sold separately) allow controls to accept a range of input voltages and current. Mount to the bottom of the control.
