Schneider Push Buttons, Switches, Emergency Stops and Pilot Lights
As the global leader in push buttons, switches, and pilot lights, Schneider Electric’s Harmony range sets the industry standard for operator efficiency and reliability. Designed to provide robust, safe, ergonomic, and intuitive control of machines and production lines, Harmony products also include smart, connected IoT-enabled devices that collect and analyze data, empowering customers to make smarter decisions.
Push buttons offer advanced functionality beyond conventional switches, making them widely used in industrial applications. Unlike typical switches that perform only one function, push buttons can mechanically link to other devices, allowing for versatile and precise control.
The most common push button switch types are Single Pole Single Throw (SPST), Single Pole Double Throw (SPDT), Double Pole Single Throw (DPST), and Double Pole Double Throw (DPDT). An SPST switch, with two terminals, opens or closes one circuit, ideal for simple ON/OFF control such as powering a motor. SPDT switches have three terminals and can control two separate circuits, enabling actions like switching between LEDs or toggling equipment between sleep and active modes. DPST and DPDT switches control two circuits simultaneously, offering more complex control options for industrial systems.
