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

Limit Switches

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

Sensor Switches

Sensor Switches

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

Magnetic Switches

Magnetic Switches

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

Light Switch Sensors

Light Switch Sensors

Automatically turn lights on and off when you enter and exit rooms

Tilt Switches

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

Light Dimmers

Adjust the brightness of lights, even in large workspaces

Bumper Switches

Bumper Switches

Signal when overhead doors close or items reach the end of conveyors

Timer Switches

Automatically turn electrical equipment on or off after a set interval

Safety Switches

Safety Switches

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

Light Switches

Manually turn lights on and off

Relays

Electrically open and close circuits to control power to lights, motors, and other equipment

Potentiometers

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

Light Curtains

Immediately cut power to machinery when anything blocks the light beam

Terminals

Attach to the end of wire to connect circuits in control panels, motors, and small machines

Fluid Handling

Humidity Controllers

Humidity Controllers

Monitor humidity and control it by automatically turning equipment on and off

Temperature Switches

Temperature Switches

Turn heating equipment on or off at a specified temperature

Temperature Controllers

Temperature Controllers

Precisely regulate process temperatures; more accurate than temperature switches

Pressure Switches

Pressure Switches

Activate controls, set off alarms, and power equipment when a set pressure is reached

Vacuum Switches

Vacuum Switches

Activate controls, set off alarms, and power equipment when a set vacuum is reached

Differential Pressure Switches

Differential Pressure Switches

Activate controls and alarms when the pressure difference between process lines exceeds a setpoint

Pressure and Vacuum Switches

Pressure and Vacuum Switches

Activate controls, set off alarms, and power equipment when a set pressure or vacuum is reached

Directional Control Valves

Directional Control Valves

Manage the flow of fluids to move equipment in air- and hydraulic-powered systems

Flow Switches

Turn equipment on or off when flow rate reaches a set point

On-Off Valves

Start and stop flow through a line

Flow Transmitters

Flow Transmitters

Send flow rate measurements to PLCs, data loggers, and remote displays

Pressure and Vacuum Transmitters

Pressure and Vacuum Transmitters

Convert pressure and vacuum measurements into a signal sent to remote displays and controllers

Fabricating and Machining

Abrasive Blaster Safety Switches

Abrasive Blaster Safety Switches

Shut off abrasive blasters if the operator loses control; also known as deadman switches

Lighting

Light Sockets

Install or replace sockets in fixtures for standard household, tubular, compact, or miniature bulbs

Heating, Ventilation, and Air Conditioning

Thermostats

Connect to heaters, fans, and air conditioners to control the temperature
