ABSTRACT:
A pool pump controller includes a pneumatic pressure sensor having at least one port disposed to react to negative pressure within a pool's pump intake chamber. The sensor input port, which includes a check valve, is connected to a pump control switch through a pneumatic tube. The pump control switch combines aspects of a diaphragm switch and an opto-interrupter to provide high-reliability control of the pump motor in a watery environment.
