Abstract: 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.
