Hi,


I'm looking at a fault in one of these switches and it would appear that one of the SMD components has come off the board, Z1. Whether this was due to bad soldering I can't tell but there's no physical or heat damage. As Z1 is nowhere to be seen I haven't a clue what the part number is (a zener diode perhaps but what voltage)?

Servicing information on these boxes is non exisitant so I'm stuck.


Any offers.


Thanks

Bob
