Multi-position electrical switch.

摘要

The switch comprises a housing (1), an insulating board (2), a plurality of stationary contacts each formed of a pair of film electrodes arranged around a central position on the insulating board, an insulating sheet (31) arranged on the insulating board and having cushions (32a-32h) expanding over the stationary contacts, movable contacts (33a-33h) inside the top of the cushions and forming switch elements with the stationary contacts, and an operation button (34) having pressing surfaces for driving each switch element by pressing said cushions, arranged tiltably and having projections (34i, 34j-34m) arranged on its bottom at positions corresponding respectively to the central position and to intermediate positions between the positions of the cushions for preventing the simultaneous operation of the switch elements.
