Abstract
The utility model discloses a photoelectric rotary switch, comprising a casing 1, a rotary unit 2 arranged in the casing 1, a disk 4 arranged on the rotary unit 2, a photoelectric detection system secured to the casing 1, wherein, the photoelectric detection system composes an emitter 3 and a receiver 5. The photoelectric rotary switch can effectively improve the accuracy of switch signal output, and reduce the false action rate of the control component. Compared to conventional key switches, the photoelectric rotary switch has higher acting speed and operates more stably and reliably.
Description
Technical field
The utility model relates to a kind of opening and closing that come control switch with the impartial step-length that changes rotary body, and the reversible photoelectricity rotary switch of on off state.
Background technology
The control switch that uses in automation control systems such as Industry Control, electric instrument, Medical Devices at present normally adopts fine motion button or conductive rubber switch, and this mode is easy to take place key jitter or malfunctioning and bring unnecessary economic loss even the accident that can so meet accident when using on precision instrumentation.
Summary of the invention
The purpose of this utility model is to provide a kind of photoelectricity rotary switch, and it not only can adjust apparatus operating parameters with very high precision, and can reduce the malfunction rate of control signal, increases work efficiency and improves the reliability of equipment.
The purpose of this utility model realizes by following technical proposal.Above-mentioned photoelectricity rotary switch, it by casing, be contained in rotating shaft in the casing, be contained in its periphery of upper edge, plane of the rotating circular disk in the rotating shaft, above-mentioned rotating circular disk and equidistantly be equipped with identical grating through hole, be packed in the photodetector system on the body, above-mentioned photodetector system is made up of reflector and receiver, reflector and receiver install in the circuit board, lay respectively at the both sides on the above-mentioned rotating circular disk, above-mentioned emission part is made up of resistance and infrared diode, and above-mentioned receiving element is made up of phototriode.
Photoelectricity rotary switch of the present utility model has the following advantages compared with prior art: 1, because the photoelectricity rotary switch has adopted photoelectricity controlled in wireless principle, so it jitter phenomenon can not take place because of the height of switching frequency.2,, cause key jitter or malfunction so can as conventional switch, not understand when using because of the switch contact oxidation because on off state adopts the noncontact mode.
