Safety Switches

Safety Switches

Protect people by cutting power to machines when access doors open; also known as interlock switches

Sensor Switches

Sensor Switches

Detect moving objects from a distance, triggering a circuit to open or close

Tilt Switches

Trip circuits when tilted; use as position indicators, pump level controls, and limit switches

Snap-Acting Switches

Snap-Acting Switches

Open and close circuits quickly to minimize arcing and sticking; often used as door-open indicators

Potentiometers

Control speed, volume, and light intensity by varying electrical flow; also known as rheostats

Vibration Switches

Vibration Switches

Monitor vibration in machinery and shut it down or sound an alarm if levels rise

Motor Starters

Turn motors on and off and protect them from current overloads

Speed-Monitoring Switches

Speed-Monitoring Switches

Avoid downtime and machinery damage by detecting slowdowns in drive trains and conveyors

Float Switches

Start process equipment such as pumps and motors when the liquid in your tank reaches the float

Float Switch Relays

Float Switch Relays

Amplify current to actuate equipment that has a higher current rating than your float switch

Level Sensor Switches

Level Sensor Switches

Activate equipment by detecting the liquid level in a tank

Paddle Level Switches

Paddle Level Switches
