PROJOY PECS series manual change-over switch, built for reliability.

It is a purely mechanical transfer switch – no motors, no controllers, no detection electronics. Just robust, field‑proven manual operation via an external handle.

Key features:
🔹 Mechanical interlock – ensures two power sources are never paralleled
🔹 Independent OFF (0) position – visible physical break for safe servicing
🔹 Minimalist design – ultra‑low failure rate, maximum uptime

Manual switching and physical isolation. No automatic monitoring. No unnecessary complexity. Just safety you can see and trust.
