Key Switches

Key switches are electromechanical switches that can only be operated with the use of a key, which then is turned to different positions to break or complete the circuit. The different positions align with different states, such as 'ON' or 'OFF', giving a clear indicator of the state of the circuit. Key switches are typically used for operations and process that may require a higher level of safety or security clearance as they cannot be accidentally switched on or off without using the appropriate key. RS supply a range of key-operated switches from a variety of brands, including APEM, C&K, Lorlin, and our own RS PRO, as well as others.
