Abstract

A tactile switch (1) includes a base (3), an elastic conductive member (4), and a cover sheet (5). A fixed contact (2a) is provided in the base. The elastic conductive member, has a dome shape, opposes the fixed contact, and is elastically deformed to be electrically conducted with the fixed contact. The cover sheet covers the elastic conductive member. An operating protrusion (6) is provided on a face of the cover sheet at a position corresponding to the fixed contact. The operating protrusion includes an end part (6a), a root part (6b) of fixed to the cover sheet and having a diameter larger than a diameter of the end part, and a bent part (6c) connecting the end part to the root part so that a first angle (A1) formed by a side wall of the root part with respect to the face of the cover sheet is smaller than a supplementary angle (A2) of a second angle formed by a side wall of the end part with respect to the face of the cover sheet.
