While I was running the remote cable for the Inverter I thought I would fit a on/off switch for the Vast satellite receiver / PVR and the HDMI switch box as they were always in standby mode or on. The problems with them not turning off and staying in standby is that they are drawing about1.5amps all the time, The built in hard drive is always spinning making a slight hum noise, The unit was warm to touch and the display is lit up at night keeping my wife awake.
The PVR and HDMI switch box are plugged into a 12v cigarette / USB socket screwed to the wall behind it. All I did was fit the switch in the positive wire feeding the 12v cigarette / USB socket and drilled a hole in the timber panel to mount the switch so now I have control.

Rear of switch, Had to recess a hole for the switch nut as the thread was not long enough.

Back together and now I can turn it off.
