HeschenUniversal Rotary Cam Selector Changeover Switch SZW26-20/D202.2 660V 20A ON-OFF-ON 3 Position 2 Phase 8 Terminals,TUV

Used to alternately switch power between two 12v TVs from a single power stabiliser adaptor.The details of the product does not make clear that it's fine to use this for low voltage applications, but it certainly is (and has worked as above in my caravan really well).It's a very solid bit of kit too and is easily fitted and looks great when installed.Many reviewers here state the instructions too basic to understand, but I can't really see this argument given a simplistic yet idiot proof diagram is provided showing exactly what switching connections are achieved in the three switch positions (the mid position denoting all connections being off).It's a bargain and I'm really pleased...

Brilliant. Not quite did the job I wanted but a bit of extra cable and it did the job

I wanted this to replace the Fwd/Off/Reverse switch on my little lathe, Would be 5 stars if a wiring diagram was included!

Good quality change over switch.

Does exactly what its supposed to. Wiring was a bit tricky but I just copied a yt video. Looks smart and works perfectly. Used to swap between 12v system running off ecoflow delta 2 and festool batteries (stepped down).

Brought to switch between solar inverter and grid, looks good and a good price

This is a good switch that works very well. Only thing missing is a wiring schematic, had to spend a while with a continuity meter working out which terminal is which. I think that's pretty unforgivable really and a shame as I would have given it 5 stars otherwise.

I bought this switch for my caravan. I installed it to change over from solar panels to the mains electricity. Works wonders
