BM869S not reading correct voltage

<< < (4/12) > >>

joeqsmith:
You work on electronics without proper ESD protection? 

I see three photos of one side of the switch, none of the other. 

coromonadalix:
?  is the dial has being flipped by mistake or a contact has flown into space ???

you have 3 pairs of pcb traces and i see only 2 contacts = 2 pairs ???   

you seem to miss the one near the center hole ??? m or more than 3  since you have some level shifting in the pcb traces


search for teardown videos

this site has photos who does show 2 contacts ???

Fungus:
You're definitely missing some switch contacts here...

(I think there should be four of the gold spring things on the dial)

Phew, that's right on the edge.
For such regions, we install dedicated "tropicalized" measuring devices in our system, for example.

coromonadalix:
yeah    but  see my link on my post    we see only 2 contacts

a simple dial miss-alignment in functions ???
