Abstract

A system for controlling water flow through a shower head includes a shower mat made of resilient material having a transmitter, an electrical power supply, and a switch embedded and hermetically sealed therein. The switch, when activated by a bather, sends a power pulse provided by the power supply to the transmitter, which transmits a control signal in response to each received power pulse. Separate from the shower mat, the system also includes a low-voltage DC power source, a receiver powered by the power source, and control logic which alternately activates and deactivates a driver transistor of a solenoid control circuit in response to the receipt of control signals received by the receiver from the transmitter. A solenoid-controlled valve in line with water flow to the shower head has a control solenoid with an input that is coupled to the low-voltage power source through the driver transistor.
