A locking claw for locking the switch is provided at one end side, and a lower surface of the changeover switch is locked to the locking claw, and a switch mounting hole provided with a switch operation surface provided on the reflection plate. And is exposed on the lower surface side of the reflection plate.

[0007]

According to the above construction, the changeover switch is locked and supported at one end of the columnar resin spacer to restrict the vertical movement, and the switch body is fitted into the switch mounting hole of the reflector. It is inserted so that the movement in the left and right direction is restricted. In addition, the resin spacer also has a structure that penetrates the circuit board and locks and supports both sides of the body, and does not use any screw fastening, so that assembly is extremely simple. Further, since the operation surface of the switch is located below the reflection plate, it is not necessary to turn each hand over the instrument body.
