This is an old mechanical, rotary drum & rocker switch, stream switcher. It was designed as a 5 streams or 10 streams unit.

RIGAS can fabricate a replacement. We utilize more modern parts (i.e., a PLC replaces the mechanical timers; status lights are replaced by LEDs). Other options are available too, just ask.
