ABSTRACT:
A pressure detection switch includes a membrane switch and a key pad arranged on the membrane switch. The membrane switch includes first and second insulation sheets arranged to face each other. An electric circuit, which includes a first electrode and a voltage-dividing resistor, and a resist film, which protects the electric circuit, are formed on the lower surface of the first insulation sheet and above the second insulation sheet. The resist film has an opening through which the voltage-dividing resistor is exposed from the lower surface of the first insulation sheet.
