Alternating Relays are used in special applications where the
optimization of load usage is required by equalizing the run time of two
loads. This alternating action is initiated by a control switch, such as
a float switch, manual switch, timing relay, pressure switch, or other
isolated contact. each time the initiating switch is opened, the relay
contacts will change state alternating the two loads.

Alternating Relays with cross−wired contacts can operate as normal
alternating relays when one control switch is used. If a second lag
switch is used, the relay will simultaneously operate two loads on a first
ON, last OFF basis.
