Thanks for the update, and pics or it didn't happen😁

Haha,...... it's not happened yet but when it has I'll post a pic!! Am busy with other projects right now :-)

Now I am facing the same problem with my 4002. It's heartbreaking such a small part is keeping me from completion. Can anyone suggest a solution? I think finding a B&O replacement will be very difficult and time consuming. I guess B&O no longer carries spare part? I have replaced and refurbished so many other parts on my table, but this one is the hardest to figure out!

Check earlier responses to this thread, I posted some pics of micro switches, Martin agreed the numbers 33 to 36 may be a possibility.

I saw that post, Soren. Could you tell me where that photo comes from. What company, there are some interesting switches there but I didn't see any identification as to what company was offering them.

Looking at the switch, it seems to be a two position switch. At rest, it makes contact with one point and then when the arm hits it, it switch over to make contact with another point. Is this correct? I'm trying to work out what kind of switch to get.

Thanks for your help!

I dont remember where I found that pic, but just search the web for micro switches, you will need one small enough to fit into the the BG, Nearly all micro switches comes with 3 wire connections:  one is "0" the other 2 is one NC and the other NO, you will need a switch with an actuator arm with a roll, I dont have a BG 4002 myself. But a pic of the PCB where the switch is located would help me to maybe help you further
