Abstract
Abstract This invention discloses a switch structure wherein a plurality of metallic contacts are recessed in a contact holding member of electrical insulating material, each contact is arranged not to overlap one another when each contact is developed on the same plane, and by bending a part not to be recessed of at least one contact a contact area is formed facing a corresponding contact area formed on the part not be recessed of another contact so as to perform a relative contacting and separating operation.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
119 words
A switch structure wherein contacts are recessed to be held, and comprising, at least one metallic stationary contact, at least one metallic movable contact, each stationary contact being associated with a movable contact, and a contact holding member of electrical insulating material for holding the stationary and movable contacts, in which each contact includes a recessed part held by the holding member, a further part to be bent relative to said recessed part, wherein the further part of each stationary contact and its associated movable contact define contact areas to perform a relative contacting and separating operation, and wherein each contact is arranged not to overlap one another when each contact is viewed in development in the same plane.
Claim 2
Dependent Claim
119 words
A switch structure wherein contacts are recessed to be held, and comprising, at least one metallic stationary contact, at least one metallic movable contact, each stationary contact being associated with a movable contact, and a contact holding member of electrical insulating material for holding the stationary and movable contacts, in which each contact includes a recessed part held by the holding member, a further part to be bent relative to said recessed part, wherein the further part of each stationary contact and its associated movable contact define contact areas to perform a relative contacting and separating operation, and wherein each contact is arranged not to overlap one another when each contact is viewed in development in the same plane.
Claim 3
Dependent Claim
56 words
A switch structure as set forth in claim 1, wherein each contact is defined in a contact collection plate which in turn comprises a punched metal plate, each contact being located on the same plane of the metal plate when viewed in its developed state, while each said contact is held in said contact holding member.
Claim 4
Dependent Claim
39 words
A switch structure as set forth in claim 2, wherein the contact collection plate includes portions to be separated, and wherein each contact is formed by cutting off each portion to be separated from the contact collection plate .
Claim 5
Dependent Claim
71 words
A switch structure as set forth in claim 3, wherein at least one opening is provided in the contact holding member to be used when cutting off a portion to be separated, said at least one opening being located at a position corresponding to a recessed part in the contact holding member of each portion to be separated by cutting off when each contact is recessed in said contact holding member.
Claim 6
Dependent Claim
49 words
A switch structure as set forth in claim 4, wherein the further part of each contact is to be bent to form a facing contact area in such a manner that each facing contact area is located on the same side in the developed state of the metal plate.
Claim 7
Dependent Claim
22 words
A switch structure as set forth in claim 5, wherein each contact includes an electro-conductive film on at least one side thereof.
Claim 8
Dependent Claim
35 words
A switch structure as set forth in claim 1, wherein the contact area of at least one stationary contact is to be bent to be orthogonal to the contact area of its associated movable contact.
Claim 9
Dependent Claim
29 words
A switch structure as set forth in claim 1, wherein the recessed part of each stationary contact is supported on a supporting member formed on said contact holding member.
Claim 10
Dependent Claim
36 words
A switch structure as set forth in claim 1, wherein said contact holding member is divided into a plurality of parts and each of said parts is connected through a connecting piece which can be bent.
Claim 11
Dependent Claim
19 words
A switch structure as set forth in claim 9, wherein said connecting piece is a part of the contact.
