Replacement Switch for Boss Pedals

Replacement Momentary Push Switch (for BOSS-style Effects Pedals)

This is a small, panel-mount momentary push switch commonly used in BOSS effects pedals. It fits into a square mounting hole roughly 0.55” × 0.55”, with an overall length of about 1.08” including the terminals. The switch is SPST momentary, meaning it only makes contact while pressed.

Basic details

• Momentary push-button switch (SPST)

• Fits standard BOSS pedal switch cutout

• Quiet operation when pressed

Typical use

• Direct replacement for worn or unresponsive footswitch mechanisms in BOSS-style pedals

• Useful for DIY pedal builds requiring a low-profile internal momentary switch

Installation

Remove the old switch, insert this one into the existing square hole, and solder the terminals to the original pads or wires. No extra modifications are usually needed.
