Ohio Electric Control Alternating Relays are designed for applications where two loads are alternately powered. This provides equal run time on the pumps. Output contacts will change state each time the control switch opens.
The control switch may be a float, thermostat, pressure switch, or timer.
The option lead/lag selector switch allows you to lock the relay in position for servicing while allowing the remaining pump to operate.
