Manual Switches

Limit Switches

When an object in motion comes into contact with these switches, it sends a signal to open or close a circuit.

Noncontact Switches

Remotely sense an object in motion to open or close a circuit.

Disconnect Switches

Cut power and keep it isolated to prevent equipment from starting up during inspection and maintenance.

Motor Control Switches

Turn motors on and off, or adjust their speed.

Potentiometers

Vary electrical flow to control speed, volume, and light intensity. Also known as variable output switches or rheostats.

Other Washdown Switches

Pressure and Vacuum Switches

Switches electrically activate automated controls or alarms in your process when a set pressure or vacuum is reached.

Level Switches

Activate process equipment such as pumps or motors when the liquid in your tank reaches a set level.
