Review on Unlock Versatility with Momentary Switch Keyed Removable Position by Mark Adams

This is a single pole, single position, snap action, normally open switch. It has two connections for pressure cable lugs. It comes with two wrenches and a nut to hold it in place. If I were being critical I would note that the contacts are on the outside diameter of the switch. This isn't usually a problem unless you deep install it. In my application, I just soldered a few wires and used heat shrink tubing to insulate them.
