Abstract

Abstract An improved clapper arm is pivotally mounted on a frame that is secured to a coil for actuating an electrical switch. The clapper arm is provided with independent fingers for depressing two pins of the switch. The fingers, which are an integral part of the clapper arm and which may be independently adjusted by bending, are located on opposite sides of a substantially centrally located pivot.

Claims Analysis

Total Claims: 15
Claim 1
Independent Claim 143 words
An electrical switch having a coil and two contactcontrolling pins, both of which are normally biased to a first position, one of said pins being moved to a second position when said coil is energized, and the other of said pins being moved to said second position when said coil is de-energized, characterized by: a clapper arm having a first leg with two independently cantilevered fingers, positioned in tandem collinearly with the pins, each of which is adapted to bear against a corresponding one of said pins to move the pin to its second position, and a pivot shaft positioned between said fingers and at substantially right angle thereto; and a second leg substantially perpendicular to said first leg, said second leg being positioned to be acted upon by said coil when said coil is energized to rotate said arm about said pivot.
Claim 2
Dependent Claim 143 words
An electrical switch having a coil and two contactcontrolling pins, both of which are normally biased to a first position, one of said pins being moved to a second position when said coil is energized, and the other of said pins being moved to said second position when said coil is de-energized, characterized by: a clapper arm having a first leg with two independently cantilevered fingers, positioned in tandem collinearly with the pins, each of which is adapted to bear against a corresponding one of said pins to move the pin to its second position, and a pivot shaft positioned between said fingers and at substantially right angle thereto; and a second leg substantially perpendicular to said first leg, said second leg being positioned to be acted upon by said coil when said coil is energized to rotate said arm about said pivot.
Claim 3
Dependent Claim 33 words
A switch of the type described in claim 1 including a leaf spring for biasing said arm to move to other of said pins the said second position when said coil is de-energized.
Claim 4
Dependent Claim 36 words
A switch of the type described in claim 1 including a frame fixed at one end to said switch and including means at the other end for pivotally supporting the pivot shaft of said clapper arm.
Claim 5
Dependent Claim 41 words
A switch of the type described in claim 3 wherein said pivotally supporting means is a pair of laterally spaced tabs having coaxially aligned openings therein, the ends of said pivot shaft being journaled in the aligned openings of said tabs.
Claim 6
Dependent Claim 28 words
A switch of the type described in claim 1 wherein said fingers are adapted to be independently bent to finely adjust the second position of the corresponding pin.
Claim 7
Dependent Claim 139 words
An actuating arm for an electrical switch of the type having an energizing coil and two contact-controlling pins, both of which are normally biased to a first position, one of said pins being moved to a second position by said arm when said coil is energized, and the other of said pins being moved to said second position by said arm when said coil Is de-energized, said arm comprising: a first leg having two independently cantilevered fingers collinearly with the pins positioned in tandem, each of which is adapted to bear against a corresponding one of said pins to move the pin to its second position, and a pivot shaft positioned between said fingers; and a second leg at substantially right angle to said first leg, said second leg being adapted to function as the clapper for said coil.
Claim 8
Dependent Claim 139 words
An actuating arm for an electrical switch of the type having an energizing coil and two contact-controlling pins, both of which are normally biased to a first position, one of said pins being moved to a second position by said arm when said coil is energized, and the other of said pins being moved to said second position by said arm when said coil Is de-energized, said arm comprising: a first leg having two independently cantilevered fingers collinearly with the pins positioned in tandem, each of which is adapted to bear against a corresponding one of said pins to move the pin to its second position, and a pivot shaft positioned between said fingers; and a second leg at substantially right angle to said first leg, said second leg being adapted to function as the clapper for said coil.
Claim 9
Dependent Claim 192 words
In a microwave, coaxial switch including a base, at three terminals mounted in tandem in the base, conductive contact blade means positioned in opposition to each two adjacent terminals, each of said blade means being movable between a first position spaced from the terminals, a separate pin means slidably mounted in the base for supporting each of the contact blade means during movement thereof, and actuation means, the energizing of which is operative to control the moving the contact blade means between the first and second positions, the improvement comprising: a. a support frame mounted on the base; and b. a clapper arm pivotally mounted on said support frame and responsive to the energizing of the actuation means, said clapper arm including means for exerting a force directly on the pin means to move the contact blade means between the first and second positions, said force exerting means of said clapper arm comprising a first finger positioned so as to engage one of the pins, and a second finger positioned so as to engage another one of the pins, said first and second fingers being positioned in tandem, collinearly with the pins.
Claim 10
Dependent Claim 192 words
In a microwave, coaxial switch including a base, at three terminals mounted in tandem in the base, conductive contact blade means positioned in opposition to each two adjacent terminals, each of said blade means being movable between a first position spaced from the terminals, a separate pin means slidably mounted in the base for supporting each of the contact blade means during movement thereof, and actuation means, the energizing of which is operative to control the moving the contact blade means between the first and second positions, the improvement comprising: a. a support frame mounted on the base; and b. a clapper arm pivotally mounted on said support frame and responsive to the energizing of the actuation means, said clapper arm including means for exerting a force directly on the pin means to move the contact blade means between the first and second positions, said force exerting means of said clapper arm comprising a first finger positioned so as to engage one of the pins, and a second finger positioned so as to engage another one of the pins, said first and second fingers being positioned in tandem, collinearly with the pins.
Claim 11
Dependent Claim 61 words
The improvement in accordance with claim 7 wherein said support frame is a substantially L-shaped member having first and second legs, the actuation means being secured to said first leg, one end of said second leg being used for securing said support frame to the base, the other end of said second leg including means for pivotally supporting said clapper arm.
Claim 12
Dependent Claim 63 words
The improvement in accordance with claim 7 wherein said support frame is substantially L-shaped and includes a pair of laterally spaced tabs at one end thereof, said tabs having coaxially aligned openings therein, said clapper arm being substantially L-shaped and having a transverse shaft integral with one leg thereof, the ends of said shaft being journaled in the aligned openings of said tabs.
Claim 13
Dependent Claim 24 words
The improvement in accordance with claim 9 wherein said shaft is intermediate said tandemly positioned fingers and is perpendicular to the longitudinal axis thereof.
Claim 14
Dependent Claim 31 words
The improvement in accordance with claim 7 wherein there is further included a spring for exerting a force on one of said fingers in a direction towards the pin associated therewith.
Claim 15
Dependent Claim 21 words
An improvement in accordance with claim 10 wherein said spring is a leaf spring having one end secured to said frame.
