Guitar Effects Latching Button 3PDT Foot Switch

This is a latching 3-pole, double-throw switch that works well for guitar pedal effect pedals. This 9-pin switch can also be used to enable True Bypass i.e., to completely bypass the effect circuitry when your effect is turned off.

A three pole, double throw (3pdt) switch comprises three single double throw (spdt) switches controlled by one foot switch. The comparison between SPST, SPDT, and 3PDT are shown in the below switch diagrams belo:
