The wire 11 has a first end which is electrically connected to the switching device 12; a second end of the wire 11 passes through the open end of the end of the shell 10 which is close to the PCB board 7 to connect to the PCB board 7. The open end of the shell 10 which is close to the switching device 12 is provided with a wire stopper 9 for fixing the wire 11, thereby preventing the wire 11 from swaying relative to the shell 10, hence avoiding the wire 11 from being worn and increasing the service life.
