Set of 3 - 9PIN 3PDT Footswitches (3PDT, 3-circuit 2-contact) These are standard footswitches often used when building guitar effects. They can also be used for true bypass switching. This is an alternate type (latching type) that is often used in guitar effects, turning ON when stepped on and OFF when stepped on again. Please note that this is not a momentary type that is ON only when pressed. Includes 2 nuts, a plastic washer, and a star washer.
