Abstract

PURPOSE:To provide a detecting switch with high reliability by bringing the contact portion of a movable terminal member into direct resilient contact with a fixed terminal member through the operation of a control, when the fixed terminal member is not in contact. CONSTITUTION:When a control piece 5 waiting to be operated is pressed and moved in the direction of the arrow, a movable terminal member 4 is forcibly moved in the direction of the arrow while deflecting downward with its fixed contact portion 4a serving as a fulcrum. This movement followed by the deflecting action allows the folded portion 4b of the movable terminal member 4 to move slightly downwards while making sliding contact with the interior wall face of a case. Through this moving process, a movable contact portion 4c makes slight sliding contact with one fixed terminal member 3 while making direct resilient contact. This resilient contact provides an electrical connection between both fixed terminal members 2, 3, and the state change of a subject for detection can be detected according to the connection.
