SANOXY 1 Pack of 3 Remote Control Power Switches

so as a follow on to the last video this is another one of these remote control mains power units which is developed a fault so so you can see on here sometime written a question mark on here because this was not working correctly and in this case what happens is the relay does click but then it randomly can switch itself off so I was doing some tests this morning and it does actually switch the power on to the bottom is plugged into the socket but then sometime later maybe a couple of minutes later you hear the click of the relay and the LED is still lit but the unit's not providing power to the device setting on go so I think the capacitors bad in here but it's a slightly different behavior to what i was getting with the other unit which was total failure so i thought i would just get the multimeter out and measure the capacity capacitance value and then we can see what's going on her
