On/Off Momentary Keyswitch | KS-2

The RGL KS-2 is a momentary ON/OFF keyswitch for controllers that require a temporary key-operated signal rather than a maintained selection. It is commonly used with automatic door, access control and building-control inputs where the controller performs the latching or logic function.

The stainless steel faceplate provides a durable professional finish, while voltage-free NO/NC contacts make the switch suitable for interfacing with a wide range of compatible control circuits.
