Abstract
A switching device includes a switch body, a base plate provided in the switch body, an operation knob provided in the switch body so as to pushed therein, an elastic member arranged on the base plate, the elastic member including a contact holder portion, which is elastically deformable, for switching a first switching member in response to a pushing operation of the operation knob, a switching knob provided near the operation knob; and a contact holder for switching a second switching member in response to a switching operation of the switching knob, the contact holder slidably arranged on the base plate.
Claims8
A switching device comprising:
- a switch body;
- a push-type operation knob in the switch body, the operation knob having an approximate rectangular shape to provide four adjacent corner areas, the operation knob further having operation parts between each of the adjacent corner areas;
- and
- each of the corner areas having a switching member, the switching members being disposed and electrically connected to one another so that in response to depressing one of the operation parts the switching members at the adjacent corner areas of the operation part are operated and a normal switching operation occurs, and in response to depressing the operation knob in such a manner that only one of the switching members is operated a normal switching operation is prevented.

- each of the corner areas having an elastically deformable contact holder portion;
- at least one movable contact is mounted to each contact holder portion;
- and
- at least one stationary contact is mounted to the base plate in relative disposition to each movable contact, the stationary contacts being electrically connected to one another so that in response to depressing one of the operation parts the movable contacts at the adjacent corner areas of the operation part are brought into contact with the corresponding stationary contacts and a normal switching operation occurs, and in response to depressing the operation knob in such a manner that only one of the moveable contacts comes into contact with one of the stationary contacts a normal switching operation is prevented.
