C-Bus™ Changeover Relays are DIN-rail mounted devices with four independent, voltage free, changeover relay contacts.

Changeover Relays are designed to operate three-speed motors and two-way motor control devices. Some of their most common applications include operating motorized blinds, shutters, curtains and skylights (open/closed) where they provide a much simpler alternative to traditional and obtrusive relay interlocking systems.
