Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
146 words
A push-button switch comprising a housing provided with a suppoRt means for supporting a magnetic member at an upper portion of said support means; a magnetic switching element fixedly positioned in said housing; a lower spring member contained in said housing; a magnet mounted on said lower spring so as to move up and down in said housing while its upward movement is restrained by said support means and also, while being attracted to said support means in the ordinary state; a pusher member capable of moving up and down; a first upper spring applied to said pusher member at its one end, and mounted on said magnet at its other end; and a second upper spring also mounted on said magnet at its one end and the other end positioned from said pusher member at a first predetermined pushed down displacement of said pusher member.
Claim 2
Dependent Claim
146 words
A push-button switch comprising a housing provided with a suppoRt means for supporting a magnetic member at an upper portion of said support means; a magnetic switching element fixedly positioned in said housing; a lower spring member contained in said housing; a magnet mounted on said lower spring so as to move up and down in said housing while its upward movement is restrained by said support means and also, while being attracted to said support means in the ordinary state; a pusher member capable of moving up and down; a first upper spring applied to said pusher member at its one end, and mounted on said magnet at its other end; and a second upper spring also mounted on said magnet at its one end and the other end positioned from said pusher member at a first predetermined pushed down displacement of said pusher member.
Claim 3
Dependent Claim
53 words
A push-button switch as claimed in claim 1, further comprising a means capable of engaging with said pusher member upon completion of the snap action of said push-button switch so that the amount of rebound of said magnet is restricted to a preselected value, whereby said magnetic switching element is prevented from chattering.
Claim 4
Dependent Claim
18 words
A push-button switch as claimed in claim 2, wherein said means is a support for supporting said magnet.
Claim 5
Dependent Claim
24 words
A push-button switch as claimed in claim 1, wherein said first upper spring has a resiliency lower than that of said second upper spring.
Claim 6
Dependent Claim
109 words
A push-button switch as claimed in claim 1, wherein said push-button is provided with a key top member changeably mounted on said push-button switch, and wherein said housing is provided with a projection from at least one side wall thereof and having a lower face, and said key top member is provided with a pair of resilient and laterally flexible pawls on at least one side wall thereof, each of said pawls having inwardly protruding claws provided with a top margin which is engageable with said lower face, whereby said pair of claws removably slip into engagement with said lower face due to the lateral flexibility of said pawls.
Claim 7
Dependent Claim
122 words
A push-button switch as claimed in claim 5, wherein said push-button switch is provided with engaging projections formed at the top of said housing, and electrical leads projecting from said projection and capable of being connected to an electrical power source, further comprising a lamp indication unit composed of a socket portion which is provided with lamp containing portions, engaging slots engageable with said engaging projections of said housing and through-holes provided for passing of lead wires therethrough and a wire portion and at least one lamp and a wire connected to said lamp at its one end and to one of said electrical leads of said push-button switch at its other end while extending through said through-holes of said socket portion.
Claim 8
Dependent Claim
25 words
A push-button switch as claimed in claim 6, wherein said socket portion is made of a heat-resisting, transparent easily colored, elastic and easily moldable material.
Claim 9
Dependent Claim
75 words
A push-button switch as claimed in claim 1, wherein said housing includes two vertical walls facing each other, and a plurality of electrical leads molded in said housing so as to be disposed in a vertical plane perpendicularly intersecting the center of said both vertical walls, and is formed into a shape symmetrical with respect to said vertical plane so that molding of a plurality of said housing is capable of being continuously carried out.
Claim 10
Dependent Claim
58 words
A push-button switch as claimed in claim 1, wherein said support means consists of a magnetic member provided with left and right hand portions extending downward from a portion for supporting said magnetic material in the direction of the movement of said magnet so that closed magnetic circuits are provided for the magnetic flux emitted by said magnet.
Claim 11
Dependent Claim
80 words
A push-button switch as claimed in claim 9, wherein each of said left and right hand portions is provided with a first pair of mounting legs at the end thereof which are engageable with stepped portions formed in said housing by forcibly parting said first mountiNg legs, and a second pair of mounting legs in a form projecting from the middle of said first mounting legs which are to be used for fixing said push-button switch in a required position.
