Low-power consumption door lock button

The invention discloses a low-power consumption door lock button. The low-power consumption door lock button comprises a base, a reset spring fixed to the base, a printed circuit board (PCB) fixed to the base, a button body connected to the reset spring, induction coils arranged on the PCB and microswitches arranged on the PCB. The induction coils are connected with an external door lock main control panel. The PCB is connected with an external battery device. The top end faces of the microswitches are provided with touch points and connected with elastic pieces. A button head extrudes the elastic pieces. Due to the arrangement of the microswitches, the microswitches are switched on when the button head is pressed down, and the PCB connected with the battery device is powered on and activated to be in a working state; when the button head is not pressed, the microswitches are off, the PCB is not powered on, and the door lock button is in a sleeping state temporarily. Accordingly, the purpose for reducing the power consumption is achieved, the service life of a door lock and the battery device is prolonged, and the function for reducing the cost is achieved.
