Problems solved by technology

[0002] The technology commonly used in non-contact switches is to use the infrared tube module, distance measuring module, pyroelectric sensor module, etc., where the infrared tube module and the distance measuring module cannot identify the operation of the human body. When a foreign object touches the detection port It is easy to cause non-subjective misoperation, and the detection angle of the pyroelectric sensor module is too large, so it cannot be used directly by the user without structural design. The non-contact switch can effectively avoid cross-infection and prevent the spread of diseases, and is widely used in elevators. Switches, light switches and other fields

Abstract

The invention discloses a non-contact control type switch, and particularly relates to the design of a non-contact switch, in particular to the aspect of structural design improvement of the non-contact control switch by utilizing a pyroelectric sensor. The non-contact control type switch comprises a mainboard bottom cover, a panel, a main control board and a pyroelectric sensor module, A cavity is inside the mainboard bottom cover and is used for installing the main control board, the bottom surface of the mainboard bottom cover is provided with a cable through hole for a cable to pass through and is connected with the back surface of the panel through a screw; the left side of the panel is provided with a blocking column used for blocking light, the right side is provided with a sensor stand column, a cavity used for installing the pyroelectric sensor module is reserved inside, and two side columns are parallel in a panel plane. The main control board is externally connected with a power supply, is fixed in a cavity formed by the back of the panel and the mainboard bottom cover through screws and is used for controlling on-off of the switch; the pyroelectric sensor module is installed in a cavity of the sensor stand column on the right side of the panel through a structural part and connected with the main control panel through a flat cable. The advantage of the invention isthat the non-contact control of the switch is realized.
