Description

Technical Field

[0001] The utility model relates to the technical field of infrared induction switches, in particular to a high-sensitivity intelligent infrared induction switch. Background Art

[0002] The infrared sensor switch is an automatic control switch based on infrared sensing technology. It realizes its automatic control function by sensing the infrared heat emitted from the outside world. It can quickly turn on various electrical equipment such as lamps, automatic doors, and burglar alarms.

[0003] Some existing infrared sensor switches need to be installed in a dark box during installation. During installation, the bolts need to be passed through the holes of the mounting plate and then aligned with the screw holes in the dark box. However, due to the sight obstruction of the mounting plate, it is difficult for the staff to align the screws, and the operation is more troublesome. Secondly, during disassembly and maintenance, the cover plate needs to be pried open with tools to expose the bolts before disassembly. The cover plate is snap-on, and improper operation can easily damage the cover plate. Utility Model Content
