12mm SPST key switch

Nice little 12mm diameter two-position key switches. Simple single pole on-off type switch, with red and green marker dots to signify the positions.

Made mostly from plated brass. Comes with two keys. Ideal for where you need to stop unauthorised switching of a device.

These are not high security key switches, but they can't be operated without the key (i.e. they can't be turned with a screwdriver, for example).
