Abstract
An electrical control system for operating a toilet flushing device includes an electric operator, a source of power for the operator and a detection system for detecting the presence of a user of a toilet device and upon detection thereof connecting the source of power to the electric operator. The detection system includes an infrared transmitter and an adjacent infrared receiver, with the receiver being sensitive to infrared radiation reflected from a toilet device user. There is a refracting element positioned in front of the transmitter and receiver to bend the transmitted infrared radiation beam to a desired angle relative to the initial direction of the transmitted beam and to bend a reflected beam from a toilet device user to a direction wherein it is generally parallel to the initial transmitted beam.
