Switch module, electronic device using the same and method for manufacturing the same

An electronic device, comprising:

• an outer casing having an opening;
• and
• a switch module disposed inside the outer casing, wherein the switch module comprises:
• a circuit board;
• an IR light receiver disposed on the circuit board for receiving an infrared light;
• at least one light emitting unit disposed on the circuit board for emitting a visible light;
• and
• a cover for covering the IR light receiver, wherein the cover comprises:
• a first casing for shielding the IR light receiver;
• and
• a second casing connected to the first casing, wherein the transparency of the second casing is larger than that of the first casing, and the second casing receives the visible light and then the visible light is emitted to the outside of the opening,
• wherein the opening exposes a portion of the first casing and the second casing.

A method for manufacturing a switch module, comprising:

• disposing an IR light receiver and a light emitting unit on a circuit board, wherein the IR light receiver is for receiving an infrared light;
• forming a cover from two different materials by way of a double injection process;
• and
• covering the IR light receiver by the cover, wherein the cover is disposed in the path of a visible light emitted by the light emitting unit.
