A touch switch including: a conductive member for which voltage is applied from a plurality of locations for detecting presence or absence of a touch and a touch position on the conductive member of a conductor to be detected based on an electrical conduction status of the conductive member; and a detection-level changing mechanism for changing a detection level of the electrical conduction status of the conductive member due to the touch of the conductor on the conductive member. The presence or absence of the touch and the touch position on the conductive member of the conductor is detected if the detection level meets a predetermined condition.
