Abstract
Abstract A miniature push-button switch having and improved switch body wherein a plurality of fixed contacts are each formed by bending an electrically conductive plate material to have one end acting as a contact portion, for contacting a movable contact which is adapted to slide in the longitudinal direction of the switch, and the other end acting as a switch terminal. The switch terminals are arranged in order along the direction substantially perpendicular to the longitudinal direction of the switch and comprise a normally open, NO, switch terminal, a common, C, switch terminal and a normally closed, NC, switch terminal interposed between the NO switch terminal and the C switch terminal.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
292 words
A miniature push-button switch comprising: a housing; first, second and third contact members comprising a normally open, NO, contact member, a normally closed, NC, contact member and a common, C, contact member, respectively, which are arranged in fixed positions within the housing substantially along a line extending in a longitudinal direction of the housing; first, second and third terminal members comprising a NO terminal member, a NC terminal member and a C terminal member respectively, which are connected to the respective contact members and are arranged within the housing substantially along a line perpendicular to the longitudinal direction, said second terminal member being positioned between said first and said third terminal members; a movable contact member which is movable within the housing in a longitudinal direction in contact with the contact members such that the movable contact member couples said third contact member and said second contact member in a first position, and said movable contact member couples said third contact member and said first contact member in a second position; a switching element for moving said movable contact member, said switching element being movable within said housing in the longitudinal direction; and a push button for moving said switching element, said push button being arranged in one end portion of said housing and being movable in the said longitudinal direction, wherein said switching element is moved from said first position to said second position by pushing said push button, said contact members and said respective terminal members are integrally formed by an electrically conductive plate material such that surfaces of said contact members are substantially perpendicular to surfaces of said terminal members, and said terminal members composed of the electrically conductive plate material are arranged substantially in parallel with one another.
Claim 2
Dependent Claim
292 words
A miniature push-button switch comprising: a housing; first, second and third contact members comprising a normally open, NO, contact member, a normally closed, NC, contact member and a common, C, contact member, respectively, which are arranged in fixed positions within the housing substantially along a line extending in a longitudinal direction of the housing; first, second and third terminal members comprising a NO terminal member, a NC terminal member and a C terminal member respectively, which are connected to the respective contact members and are arranged within the housing substantially along a line perpendicular to the longitudinal direction, said second terminal member being positioned between said first and said third terminal members; a movable contact member which is movable within the housing in a longitudinal direction in contact with the contact members such that the movable contact member couples said third contact member and said second contact member in a first position, and said movable contact member couples said third contact member and said first contact member in a second position; a switching element for moving said movable contact member, said switching element being movable within said housing in the longitudinal direction; and a push button for moving said switching element, said push button being arranged in one end portion of said housing and being movable in the said longitudinal direction, wherein said switching element is moved from said first position to said second position by pushing said push button, said contact members and said respective terminal members are integrally formed by an electrically conductive plate material such that surfaces of said contact members are substantially perpendicular to surfaces of said terminal members, and said terminal members composed of the electrically conductive plate material are arranged substantially in parallel with one another.
Claim 3
Dependent Claim
29 words
The switch of claim 1, wherein said second and first contact members are each disposed opposite said third contact member in a direction substantially perpendicular to the longitudinal direction.
Claim 4
Dependent Claim
21 words
The switch of claim 1, wherein said fixed contact members and said movable contact member are arranged over said terminal members.
Claim 5
Dependent Claim
31 words
The switch of claim 3, wherein said respective integral members composed of said respective contact members and terminal members, are partially embedded in a switch body formed of synthetic resin material.
Claim 6
Dependent Claim
22 words
The switch of claim 4, wherein said third contact member is positioned between said first contact member and said second contact member.
Claim 7
Dependent Claim
62 words
The switch of claim 5, comprising switching element control means for controlling said switching element such that said switching element may be maintained in said second position in an ON mode and said switching element may be released from said second position to said first position when changing from an ON mode to an OFF mode, by movement of said push button.
Claim 8
Dependent Claim
71 words
The switch of claim 6, further including illuminating means comprising an illuminant mounted on said switching element, a pair of fitments mounted on said switching element, formed of an electrically conductive material, and electrically connected to said illuminant, and a pair of illuminant terminals, said fitments being contacted by said illuminant terminals in said second position of said switching element, and being separated from the same in said first position thereof.
Claim 9
Dependent Claim
20 words
The switch of claim 7, wherein said illuminant terminals are held by an illuminant terminal assembly disposed within said housing.
