Electrical

Manual Switches

Manual Switches

Everything from toggle, push-button, and rocker switches to foot switches

Snap-Acting Switches

Snap-Acting Switches

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

Vibration Switches

Vibration Switches

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

Limit Switches

Turn equipment on or off when objects touch the actuator; often used for conveyors and bin filling

Magnetic Switches

Magnetic Switches

Actuate when a magnet comes within sensing distance; often used to detect when doors or windows open

Motor Switches

Turn motors, lighting, and electric heat circuits on and off

Tilt Switches

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

Sensor Switches

Sensor Switches

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