Can a switch just cause bypass pop on its own?

[Nitefly182]

I recently built a fuzz and its got terrible bypass pop which is something my other pedals do not have. Those pedals don't necessarily have pulldown resistors either. I used a switch that I pulled from another build and one or two of the lugs may have gotten a little hotter than necessary during desoldering and cleaning. Is it possible that the switch might be popping because of this? I added a 1.3 meg resistor from the circuit input lug on the switch to ground but that didn't kill the pop. Would replacing the switch help? I checked all the connections with a DMM and they are all switching properly. Its a MKIII tonebender so I dont think anything in the circuit would cause pop on its own.

Sometimes you get a sort of microphonic switch.
The mechanical action of the switch is audible as
a clack or tick.
If you aren't getting any voltage on the in/out lugs of the
switch in bypass/active then I'd say it's the switch itself.
If you are getting voltage on the lugs then the pulldown
isn't doing it's job and or the in/out cap is leaky which
is not uncommon.

I have this problem from time to time with pedals that are always on my pedal board. But the clicking noise isn't always there every time I step on a switch. It seems to have something to do with where I am at the time when this happens. I sometimes wonder if it's possibly power ground related since it seems to depend on where I am when this happens (as in home or somewhere else).
