It is a three-position rotary switch which is actuated by key selectors to switch between ‘on and off’, ‘reset’ and ‘neutral. The switch features a double break system, meaning it mechanically disconnects when switched to neutral position. It is installed in control or distribution panels to arbitrarily interrupt power supply or reset motors and circuits. It is rated for 3A and 250V.
