Abstract
A control apparatus for turning on and off an electrical load device which includes an enclosure having open top and bottom ends with a flexible member searingly connected inside the enclosure, the flexible member having top and bottom sides. A drive magnet is connected to the top side of the flexible member. The control apparatus further includes a mounting member carrying a switch and a pivotally mounted driven magnet. The pivotally mounted driven magnet and the drive magnet being positioned and arranged such that when fluid enters the open bottom end of the enclosure and applies pressure to the flexible member, a portion of the flexible member moves from a first position to a second position, carrying the drive magnet and bringing it into a repelling orientation with the driven magnet, which is repelled from the drive magnet and pivotally engages with the switch to operatively change the switch from a first state to a second state. The switch is operably connected to the electrical load device.
