Hi,   use the    button!!

Look up "switch pop", and terms like that.  There are many, many articles on the problem, which is generally caused by different voltage levels being present on your input and the input to the effect.  When you switch, you cause a very small arc to occur as you equalize them.  A lot of times, a 1M resistor from the input of the effect to ground solves the problem.  That's what the 1M is usually there for, in many effects schematics.
Of course, there could be some other problem, a wiring, error, but let's start simple 

Hope this helps, good luck!

thanks mike.
I already put 1M resistor on the input and also capacitor on the switch but still I can here the pop noise. I used taiwanese foootswitch 3PDT same as the fulltone.
I also used 12ax7 valve on the last stage of my effects for tube sounding.
Again thanks.
