The electronic alternating relay is designed to replace mechanical
style devices used in control applications requiring a duplexing
or alternating action of the control circuits to operate pumps,
compressors, etc. This is achieved by activating a control switch
which is common to one side of the input control voltage. The
output contact of the relay(s) change state when this switch is
opened (on de-energization of the control circuit). When the control

initiate switch is actuated and released or opened, the relay will
change state. The next time the initiate switch is actuated, it will
change back to its original state. Two red LED’s located on the top
of the dust resistant enclosure provide the status of the relay. A 3
Position Selector switch is installed for selection of normal opera-
tion (alternating) or selection of lead or lag load.
