Low-profile switch operable by rotation and pressure - has pushbutton which can be rotated to operate rotary switches and pressed to actuate elastic contact

摘要

Circuit patterns (42a-42c) of two rotary switches and a push-switch are deposited on both sides of a wafer (42) in a two-part housing. On the inner base of the lower part (41) a shaft (41a) is erected to project through an aperture (42d) in the wafer. A rotary plate (43) on the shaft (41a) carries a contact wiper (44b) for the underside pattern (42b). A tubular elastic contact piece (45) surrounding the shaft (41a) is operated by button (46). ADVANTAGE - Double function of rotary switch and pushbutton is achieved with low overall thickness, simple construction and ease of operation.
