Description

Light control panel of RS485 bus communication

Technical Field

Electrical products in a narrow sense are often referred to as switches, sockets only in building electrical. Wall switches are commonly known as: and controlling the lamp switch. In broad terms, electrical products are intended to cover a wide range of devices that typically provide electrical control of electrical power to end users, including switch outlets, circuit breakers, integrated wiring, security systems, and the like, also known as building electrical accessories (devices for holding, connecting, or opening and closing electrical circuits).

The existing wall opening structure has various forms according to functional division, and generally comprises a fixed box body and an operation part, wherein the operation part comprises a mechanical part and an electronic part. In the development of the prior art, the operation part can adopt a touch key, namely, no actual feedback activity is adopted, and feedback is carried out in a light or sound mode to indicate that the operation part is triggered. The mechanical trigger control part is also different from the prior two-point type rotation trigger switch, and various switch patterns are designed to increase the contact area and reduce the movable range. The push switch comprises a contact type push switch. The contact type push switch is a part with mechanical movable feedback, but has no form change after triggering, and always maintains a state, namely the switch is provided with a reset mechanism, and is reset after triggering. In order to conform to the existing simplified structural design characteristics, the trigger switch has smaller moving stroke, smaller moving clearance, lower noise and trigger demand force compared with the conventional paragraph switch, convenient operation and practical trigger feedback effect compared with the touch switch, and cannot judge whether effective triggering is performed.

However, this contact type push switch has a problem in that it always maintains the same external form, and even if the user has obtained the trigger feedback, it is impossible to know what connection state the switch is in the current state if there is no obvious feedback information of the controlled electric appliance for the switch triggered by another person or the switch which has not been operated for a long time. For example, a contact switch for controlling an indoor main lamp is arranged outside a door, the door is kept in a closed state, a user cannot know whether indoor lamplight is turned on or not in a non-door-opening state, a former paragraph switch can judge through the rotating position of the switch at the moment, but the switch which always keeps the initial state cannot be known, only can try to confirm by touching, and therefore certain inconvenience is caused. If the switch is an electrical device that controls a non-light fixture and does not have obvious feedback information, the open and closed states of the switch are less clear.
