Control Switch

What Are Control Switches?

Control switches are electromechanical devices used to manually or automatically start, stop, or control electrical circuits. They’re fundamental to human-machine interface systems, giving operators the power to command and monitor machinery and processes. Control switches are used across a wide range of industries—from manufacturing and automation to energy, HVAC, water treatment, and beyond.

There are several types of control switches, each designed for a specific function:
 

• Pushbuttons initiate or interrupt circuits with a simple press.
• Selector switches allow users to choose between multiple circuit paths or operating modes.
• Emergency stop switches provide a safety-critical function, immediately halting equipment in case of danger.

These switches may be illuminated, key-activated, or come with protective enclosures for harsh environments. Many models are panel-mountable and designed for easy integration into control panels and operator interfaces.
