Killswitch pedal, how to remove pop?

I've built a couple tiny kill switch pedals where I just have the switch connect the ground of the battery to the output. There's a big pop with how I have it. With this I'm disconnecting the input and output. Would that be creating the pop? Or is there something more I need to do to get the pop out of there?

Thanks for any help.

try a 1M resistor from the output tip to GND (pull-down resistor). the pop usually is the result of DC voltage on the lug or originates from mechanical noise of crappy 3pdt switches
I build pedals to hide my lousy playing.

Great, I'll try that out. Thanks!
Are there "tried and true" good switches out there? The switches in these are low-profile 3pdt from BLMS. Are those legit?

blms has generally has good quality switches. is there something else in the chain before and after the kill-switch.
before you do anything else, see if the pop is present without anything else, just guitar-switch-amp. if it doesn't pop anymore the problem is with the pedal before or after the killswitch
