The button frame has supported each subassembly of touch shimmer elevator button, should set up the convenience and firmly install the button in the calling box.

The touch sensing chip is a special touch chip, is connected with the sensing module, collects touch signals through the sensing module and outputs level signals for a peripheral circuit to use; compared with a digital-analog trigger circuit used by a common elevator touch button, the device adopts an advanced capacitance touch chip in the industry, and has the advantages of high recognition rate, chip-level filtering anti-interference, low power consumption, greatly reduced volume, high integration level and the like.

The light projection PCB board receives signals output by the touch sensing chip to control the on and off of the optical coupling switch, and further controls the on and off of the button calling indicator lamp and the low-light-level indicator lamp.

Touch low-light elevator button principle:

when a human body (hand) touches the sensing module of the elevator button, the sensing module electrode plate transmits a touch sensing chip after collecting a touch signal, the touch sensing chip outputs a level signal to the light projection PCB, the LED driving circuit in the light projection PCB lights a call indicator, and simultaneously outputs a call signal to the main control panel (the main control panel is electrically connected with the light projection PCB), so that the elevator function is called by touch, the button is normally lighted by low light when not touched, and the low light is extinguished when the button is touched to light again after the elevator arrives at a station.

Has the advantages that:

the utility model provides an elevator button is the button of touch operation, need not the physics and presses the operation, greatly reduced mechanical failure, and this button still has shimmer device, is not touched button slightly shines when this button, and touch button highlight when, also can normally operate the button under dim light or the no light condition, has promoted the visual identification rate of button.
