ActifAlpha 9mm Soft-Touch Momentary Switch
Alpha 9mm soft-touch momentary — the standard for relay bypass pedals.
Applications courantes
The small momentary switch used in relay bypass guitar pedals. Requires much less force than 3PDT — a light tap activates. Silent compared to 3PDT click. Used with relay bypass PCBs for boutique pedals. Found in Strymon, Chase Bliss, Walrus Audio, and most premium pedal brands.
