Great Key SwitchI bought 2 of these switches, and they are somewhat smaller than you might expect, but work great. You actually NEED a key to turn the switch, Other brands, make it so that you can just stick a screwdriver or a knife into the slot, and you can turn it.
I'm 12 years old, and I came up with a circuit that I could use these to turn on and off a room alarm. Work Great!
I would recommend this to anyone who needs a somewhat secure key switch.
