Alternating relays

Control relays and timers

The D85 series of alternating relays are used with one control switch per device and are available in standard 8-pin or 11-pin footprints, with either SPDT or DPDT output configurations with or without a three-position selector switch, which allows the unit to alternate the two loads as normal or lock the relay to one load or the other. By locking the alternating relay to one load, the other load can be removed for service without rewiring the first load for continuous operation.
