pb23kmed A key switch is a switch that can be activated only by the use of a key. They are usually used in situations where access needs to be restricted to the switch's functions. Key switches are available as components with solder connections, and are available with a variety of ampere ratings. They may use tubular or other specially-shaped keys for extra security. Our key switches are excellent for high traffic areas, such as offices, convenience stores, building entrances and exits.
