SWITCH 2 TRANSISTORS WITH 3PDT

MOPO
Hello,
I want to switch 2 transistors with a 3PDT (2n7000 and bs170).
It works but I have a pop when I switch and it is very unpleasant.
Would any of you have a solution to this problem?

Thank you

What circuit are you switching them in?

Switches tend to pop when DC is present. Putting the transistor right on the switch puts DC on the switch.

It would be better to build one circuit with one transistor, and another with another transistor, then switch between the two circuits.

Then you can use the circuits input and output caps and pull down resistors to prevent DC getting to the switch
