Easy to lock a light  switch either on or off
I have light switches on my security lights that need to always be powered. What a simple way to ensure they stay on. You remove 1 screw from the switch put the screw thru the lock device either on or off then screw it back in place.<br />I do a lot of electrical work in residential houses so with these, it's a cheap and easy way to lock out a device to work on it. I keep a pack in my tool belt now.<br />  You can lock on or off the light switch
