12mm On/Off Metal Key Lock Switch Prewired Key Switch Lock Maintained Latching Key Switch(Pack of 4)

A little smaller than I thought but worked great A+quality and value

Perfect. I love them. Slightly smaller than I believed from the pictures but that’s okay

Bought these for a project so I could disconnect the power. Worked great, the keys fit all of them so no worries. The only reason for 4 star, I wish they came with a lock washer, it was hard to get tight so they would not turn.

I found these on my hunt for a kill switch for my vehicle. Unfortunately with car theft being fairly easy today, I wanted a 2 piece switch, that even if found, a thief, in theory, would need the key vs. toggling the switch correctly. This was a seamless install as I soldered this to my kill wires and works like a charm. Nice know I have peace of mind having my car activated/deactivated on my terms. Also knowing I have several functional back ups in case one were to fail. Well worth the money!

Dinky, but useable.

Perfect! Easy to install! Quick delivery!

Regarding this replacement battery it's working fine without any issues..

Keys go in and out easily. On/off rotary motion is smooth. Packed in a baggy and were not damaged or scratched. Keys could be bigger but for the price, all good.
