Abstract
The two-stage rubber switch comprises a housing; an operating knob; two push bodies slidably supported by the housing; a contact wiring board having four mutually-opposing contact end portions arranged two by two under each push body; a rubber switch member interposed between the housing and the contact wiring board and having four conductive contact pieces arranged so as to be opposed to the four mutually-opposing contact end portions, respectively on the contact wiring board; and two-stage switching members in particular, such as semispherical rubber buckling portions formed together with the rubber switch member or elastically slidable push members. Further, it is preferable to use some semispherical rubber buckling portions of the rubber switch member as click feeling providing members.
Claims6
A two-stage rubber switch, comprising:
- (a) a switch housing;
- (b) a pivotal operating knob pivotally supported by said switch housing;
- (c) at least two push bodies slidably disposed at an interval within said housing, one of said push bodies being depressed whenever said operating knob is pivoted to either side.
- (d) a contact wiring board having at least four mutually-opposing contact end portions arranged two by two under each of said two push bodies;
- and
- (e) a two-stage rubber switching member interposed between said two push bodies and said contact wiring board, said rubber switching member having:
- (1) at least four roughly hemispherical rubber buckling portions located two by two under each of said two push bodies and formed with four upper surfaces brought into contact with said push bodies two by two, respectively, when said push bodies are depressed when said operating knob is pivoted to either side, and four lower surfaces two of which are two different stroke distances away from said contact wiring board, respectively;
- and
- (2) at least four conductive contact pieces fixed to said four lower surfaces of said buckling portions, respectively, so as to be brought into contact with the four contact end portions on said contact wiring board two by two, respectively, at two different stroke distances by said push body depressed by said pivotably operating knob.
