Hi, i would like to replace PCB switch to external switch, they work different, can use relay if necessary.

See diagrams bellow, how they work, how do it ? Somebody can help with diagram or tips ?



Thanks
 

if you look at the old switch, A1 is always connected to A2 as is B1 and B2. So either A1/B1 or A2/B2 is carrying the signal. So A signal goes to new A2 and B signal goes to new B2. A signal is either old A1 or A2, likewise B signal is old B1 or B2. Then:-
old A3 -> new A1
B3 -> new B1
A4 -> new A3
B4 -> new B3
Frank
P.S. you might have to short the old A1 to A2 and B1 anto B2
