Key Switches

Key Switches, which are occasionally referred to as lock switches are basically a mechanical switch that can only be activated when a key is inserted and the mechanism turned. Key Switches are usually used in situations where access needs to be restricted to a particular function such as safety and access doors, workplace mechanisms and systems or lighting in public areas to prevent them from being switched on or off.

Key Switches can be found in many industrial applications and can feature a variety of options beyond a simple on/off mechanism, including multi-position switches and selector switches which have a number of switchable options that the key switch can operate. Switching configuration types including momentary, latching, maintained, spring return and snap action which can also consist of differing contact configurations such as SPDT, DPDT and ST.  For additional security, key switches can also trap the key to prevent it being removed when in a functional position. In harsh environments, where water ingress may be an issue key switches are available with a wide variety of IP ratings.
