Thanks a lot for that

There is one query i have - you though 1 -B for reset the manual mentions:-

Check terminal I of ON/OFF/RESET selector is in
connection with PCB - A4 connector terminal 2
Check electrical continuity across terminals I & a of
ON/OFF/RESET selector when tumed to 'Reset' position

What do you think ?

It is difficult when i dont know the switch configuration - i was hoping to build up an appreciation using table view above.

Thanks Paul

if yes (to continuity) replace pcb

no idea what your trying to do with the table

you would be better off getting a switch and taking it apart.
