Dual trigger mode thin button for elevator

Abstract

The application discloses a thin button with double trigger modes for an elevator, which comprises a shell, a trigger module, a key and a button cover arranged in the shell in sequence. The key comprises a key plate and a key protrusion arranged on the upper surface of the key plate. The upper surface of the key plate is also provided with a first recess of the key plate surrounding the key protrusion. The key protrusion is provided with a first through hole penetrating through the key plate and the key protrusion. The button cover comprises a button cover bearing plate, a lower structure of the button cover arranged on the upper surface of the button cover bearing plate and a metal structure of the button cover arranged on the upper surface of the lower structure of the button cover. The trigger module comprises a PCB and a sensing metal sheet arranged on the PCB. The application further comprises a conductor spring. One end of the conductor spring is arranged against the sensing metal sheet. The other end of the conductor spring penetrates through the first through hole and a second through hole in sequence and is arranged against the metal structure of the button cover. The application can realize two trigger modes of mechanical micro-motion and capacitance sensing simultaneously.
