A switch module with improved brightness and sensitivity is provided to improve mounting efficiency of a substrate by forming an empty space outside a funnel shape. A switch module includes a substrate(110), a funnel shaped reflector(135), and a conductive elastic body(120). The substrate mounts a light emitting device. The funnel shaped reflector is installed on the substrate to place the light emitting device inside. The conductive elastic body has a vertical through hole and is installed on the substrate to include the reflector in the vertical through hole. The conductive elastic body is a barrel shaped elastic body of which a lateral surface is closed.
