An infrared sensor switch of the invention comprises an infrared sensor with a detection range, and a controller that uses the sensor to try to detect whether or not a person is present in the detection range and controls an ON or OFF state of a corresponding load unit based on each detection result obtained from the sensor. The switch further comprises a sensor block comprising the sensor, and a housing that is mounted in a wall and retains the block so that the center axis of the detection range can be rotated about a horizontal axis and as well as rotated up to at least 40 degrees downward from a forward direction of 0 degrees.

Infrared sensor switch

A control terminal includes an individual address setting section for setting a unique individual address, and a simultaneous control address setting section for setting a simultaneous control address common to the plurality of control terminals A simultaneous control address is commonly assigned to the control terminals to be subjected to group control. When an UP switch Sb or a DOWN switch Sc of an operation terminal for group dimming purpose is pushed, a transfer signal including the simultaneous control address is transmitted to a signal line Ls from a transfer controller The respective control terminals substantially simultaneously receive the transfer signal, thereby changing the intensity of illumination loads.
