Well made but tight for space inside the box
This changeover switch is nicely made inside and out with a good positive action. Be aware though that there's not much space inside the enclosure. If you want to put jumper wires between terminals (for example if you want to be able to divert mains electricity to one of two devices) then fitting all the wiring into the box gets pretty tight. There's nothing in the way of instructions with the switch, but there are good YouTube videos which will tell you what to do.
