The device is preferably provided by forming the straps 12 and trays (10b and 10c) separately as preforms (20 and 30) which are then assembled and formed into the device.

Abstract: An interlocked infrared detector wall switch which prevents use of the full "on" position that bypasses the infrared sensor, but permits changeover by service personnel to use the full "on" position. The slide switch on the wall switch assembly is partially covered by a snap-on interlock plate so that it can not be moved to the full "on" position. Removal of the interlock plate requires a screwdriver for leverage within an opening at the bottom of the interlock plate, but this opening is covered by the decorative switch plate, so that removal of the interlock plate is impossible without first removing the covering decorative plate. Casual disabling of the interlock is thereby prevented.
