Abstract
Official abstract text for this publication.
A switch structure includes: a switch member that is deformed and receives a switch input, when force of a predetermined magnitude is applied thereto; a pressing member that presses the switch member; and an intermediate member that includes a first layer and a second layer, is interposed between the switch member and the pressing member, and is plate-like, the first layer being made of a synthetic resin and abutting against the switch member, the second layer being layered on the pressing member side of the first layer and being made of a material having a rigidity higher than the synthetic resin.
First claim
Opening claim text (preview).
What is claimed is: 1. A switch structure, comprising: a switch member that is deformed and receives a switch input, when force of a predetermined magnitude is applied thereto; a pressing member that presses the switch member; and an intermediate member that includes a first layer and a second layer, is interposed between the switch member and the pressing member, and is plate-like, the first layer being made of a synthetic resin and abutting against the switch member, the second layer being layered on the pressing member side of the first layer and being made of a material having a rigidity higher than the synthetic resin, wherein at least a part of the switch member is covered by the first layer and contacts the intermediate member, when the force of the predetermined magnitude is applied to the switch member and the switch member is deformed, the part being on a side facing the first layer, wherein the switch member includes: a plunger including a convex portion that abuts against the first layer and a proximal portion that is positioned at a proximal end of the convex portion, the plunger being movable in a pressing direction of the pressing member; a contact plate that abuts against a bottom surface of the proximal portion, that has a dome shape, and that is deformed in association with movement of the plunger when the force of the predetermined magnitude is applied thereto; and a housing that accommodates therein the proximal portion and the contact plate, and wherein the first layer contacts the housing in a state where a curving direction of a top portion of the contact plate has been inverted and the contact plate has buckled. 2. The switch structure according to claim 1 , wherein the synthetic resin is an elastomer or an urethane resin. 3. A switch structure, comprising: a switch member that is deformed and receives a switch input, when force of a predetermined magnitude is applied thereto; a pressing member that presses the switch member; and an intermediate member that includes a first layer and a second layer, is interposed between the switch member and the pressing member, and is plate-like, the first layer being made of a synthetic resin and abutting against the switch member, the second layer being layered on the pressing member side of the first layer and being made of a material having a rigidity higher than the synthetic resin, wherein the switch member includes: a plunger including a convex portion that abuts against the first layer and a proximal portion that is positioned at a proximal end of the convex portion, the plunger being movable in a pressing direction of the pressing member; a contact plate that abuts against a bottom surface of the proximal portion, that has a dome shape, and that is deformed in association with movement of the plunger when the force of the predetermined magnitude is applied thereto; and a housing that accommodates therein the proximal portion and the contact plate, and wherein the first layer contacts the housing in a state where a curving direction of a top portion of the contact plate has been inverted and the contact plate has buckled. 4. The switch structure according to claim 3 , wherein the synthetic resin is an elastomer or an urethane resin.
