Hosa FSC-503 — Momentary Normally Closed Footswitch
FSC-503 Overview
The Hosa FSC-503 is a momentary, normally closed (push-to-break) footswitch designed for use with Roland and Yamaha electronic instruments and multitrack recorders. Built on the FSC-500 series platform, it features an all-metal chassis with reinforced switch construction engineered for long-term reliability in demanding performance and studio environments. A hardwired 10 ft cord provides flexible placement options without the need for extension cables. This footswitch is well suited for keyboardists, producers, and engineers who require dependable hands-free control of sustain, patch advance, punch in/out, and sequencer start/stop functions.
Rubber pads on both the top and bottom surfaces prevent movement during use, keeping the unit stable on stage floors, studio floors, or equipment racks.
