ID:	11076You can make a NVR switch from a relay and a couple of push buttons (1 make 1 break) my workshop has one for all* the power sockets, made out of a hefty 3 pole contactor, so I can kill all the power from the door on the way out. * except for one set of plugs which I use for charging batteries. I am sure you don't need a diagram, but here it is anyway.
Cheers, and a Happy New Year
