Abstract
Abstract A pushbutton switch comprising a casing and a base mounted therein for relative movement. The base has thereon a submagnetic pole plate and a Hall element for electrical connection to a switching element. A magnet is mounted in the casing in radial alignment with the Hall element and the pole piece whereby, upon relative movement between the casing and the base, the polarity of the voltage across the Hall element is varied to thereby actuate the switching element. A second magnet is mounted on the base in axial alignment with the first magnet so as to normally hold the latter and the casing floating in the air by virtue of the magnetic repulsing force.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
176 words
An electric pushbutton switch comprising a first member, a second hollow member receiving said first member for relative sliding movement between first and second positions, a magnet member mounted on one of said first and second members, a submagnetic pole plate mounted on the other of said first and second members in opposite relationship to said magnet member, said submagnetic pole plate having a Hall element mounted on the surface thereof facing said magnet member, said Hall element having its terminals adapted to be electrically connected to a switching element, and means for normally holding said one member and said magnet member in said first position, the arrangement being such that, when said one member is in said first position, one of the magnetic poles of said magnet member is positioned in opposite relationship to said Hall element and, when said one member is moved with respect to said the other member against said holding means to said second position, the other magnetic pole of said magnet member is positioned in front of said Hall element.
Claim 2
Dependent Claim
176 words
An electric pushbutton switch comprising a first member, a second hollow member receiving said first member for relative sliding movement between first and second positions, a magnet member mounted on one of said first and second members, a submagnetic pole plate mounted on the other of said first and second members in opposite relationship to said magnet member, said submagnetic pole plate having a Hall element mounted on the surface thereof facing said magnet member, said Hall element having its terminals adapted to be electrically connected to a switching element, and means for normally holding said one member and said magnet member in said first position, the arrangement being such that, when said one member is in said first position, one of the magnetic poles of said magnet member is positioned in opposite relationship to said Hall element and, when said one member is moved with respect to said the other member against said holding means to said second position, the other magnetic pole of said magnet member is positioned in front of said Hall element.
Claim 3
Dependent Claim
73 words
An electric pushbutton switch as defined in claim 1 in which said holding means comprise a second magnet member mounted on said the other member in axial alignment with the first said magnet member, said first and second magnet members having their adjacent magnetic poles which are of the same polarity so that the repulsing force between said adjacent magnetic poles is operable to normally hold said one member in said first position.
Claim 4
Dependent Claim
37 words
An electric pushbutton switch as defined in claim 2 in which said submagnetic pole plate extends the entire distance over which said first magnet member is reciprocally moved relative to said Hall element on said pole piece.
Claim 5
Dependent Claim
26 words
An electric pushbutton switch as defined in claim 3 further comprising means for guiding and limiting said relative reciprocal movement between said first and second members.
Claim 6
Dependent Claim
42 words
An electriC pushbutton switch as defined in claim 4 in which said guiding and limiting means comprise a projection on said one member and an elongated groove formed in said the other member, said projection being in slidable engagement with said groove.
Claim 7
Dependent Claim
69 words
An electric pushbutton switch as defined in claim 5, characterized in that said first member is a base having an axial flat surface on which said pole piece and said Hall element are mounted and a transverse flat surface to which said second magnet member is secured, and that said second member is a substantially cylindrical casing having an inner surface on which said first magnet member is mounted.
Claim 8
Dependent Claim
38 words
An electric pushbutton switch as defined in claim 6 in which said casing has a closed end adapted to be pressed down for the actuation of said pushbutton, said base being adapted to be mounted on a support.
