<P>PROBLEM TO BE SOLVED: To provide a pressurizing operation type switch device capable of effectively reducing a collision noise which is possible to be generated at the time of automatic recovery after pressurizing operation, and capable of generating a clear click feeling, resulting in no possibility of variation in non-operation position of an operation member. <P>SOLUTION: An operation knob 2 of a switch device 1 automatically returns to a non-operation position by the elastic recovery force of a click rubber 3 after pressurizing operation. By causing the operation knob 2 at the time of non operation to be engaged with an engaging tab (stopper part) 6c provided to a guide tube part 6d of a housing 6, the operation knob 2 is held at a predetermined non-operation position. A buffer protrusion part 3d which is protruded from the click rubber 3 is caused to press-contact to a rear surface (receiving surface) 6e of a regulation flange part 6b of the housing 6 during no operation. Consequently, at the time of automatic recovery of the operation knob 2 after pressurizing operation, a contact pressure of the buffer protrusion part 3d against the rear surface 6e gradually increases to absorb impact. <P>COPYRIGHT: (C)2013,JPO&INPIT |
