Vibration proof switch with resilient beam-deflecting actuator structure

Claim 1

A VIBRATION-PROOF SWITCH COMPRISING: A HOLLOW CASING HAVING FRONT AND REAR END WALLS WITH A SURROUNDING WALL BETWEEN THEM, THE INTERIOR OF SAID CASING BEING GENERALLY CYLINDRICAL IN FORM WITH ITS AXIS SUBSTANTIALLY NORMAL TO THE FRONT AND REAR END WALLS; AT LEAST ONE PAIR OF ELECTRICAL CONDUCTORS EXTENDING THROUGH AN END WALL AND PROVIDED WITH RESILIENT CONTACT SURFACES ADAPTED TO BE ENGAGED BY A CONTACT MEMBERE TO COMPLETE A CIRCUIT THROUGH SAID CONDUCTORS; A DISK-LIKE ROTOR MOUNTED IN SAID CASING FOR ROTATION ABOUT THE CENTRAL AXIS OF SAID CASING; A CONTACT MEMBER MOUNTED AT LEAST AT ONE FACE OF WITH SAID CONTACT SURFACES IN ONE SELECTED POSITION OF SAID WITH SAID CONTACT SURFACES IN ONE SELECTED POSITION OF SAID ROTOR AND FOR DISENGAGEMENT FROM SAID CONTACT SURFACES IN ANOTHER SELECTED POSITION OF SAID ROTOR; AND MEANS TO MOVE SAID ROTOR TO SAID SELECTED POSITIONS INCLUDING A PAIR OF RESILIENT BEAMS LOCTED ADJACENT OPPOSITE FACES OF SAID ROTOR AND HAVING THEIR OUTER ENDS FIXED IN THE SURROUNDING WALL OF SAID CASING, THEIR INNER ENDS EXTENDING RADIALLY INWARDLY TOWARD THE AXIS OF ROTATION; A PIN MOUNTED IN SAID ROTOR PARALLEL TO THE AXIS OF ROTATION AND HAVING ITS ENDS PROJECTING FROM THE FACES OF SAID ROTOR INTO FORCE TRANSMITTING ENGAGEMENT WITH SAID BEAMS TO TRANSMIT FORCES FROM SAID BEAMS TO SAID ROTOR FOR ROTATION THEREOF TO SAID SELECTED POSITIONS; AN ACTUATOR MOUNTED IN SAID CASING FOR ROTATION ABOUT AN AXIS CONCENTRIC WITH THE AXIS OF SAID ROTOR; THE OUTER SURFACE OF SAID ACTUATOR BEING GENERALLY CYLINDRICAL AND CONSTITUTING A BEAM-DEFLECTING SURFACE WITH A DISCONTINUITY THEREIN TO PROVIDE A RADIAL DEPRESSION TO RECEIVE THE RADIALLY INWARDLY EXTENDING ENDS OF SAID BEAMS IN NEUTRAL POSITION; ROTATION OF SAID ACTUATOR FROM ITS NEUTRAL POSITION CAUSING SAID BEAM-DEFLECTING SURFACE TO DEFLECT SAID BEAMS AWAY FROM THEIR RADIAL ATTITUDES AND APPLY ROTATIONAL FORCE TO SAID PIN TO ROTATE SAID ROTOR TO A SELECTED POSITION IN WHICH SAID CONTACT MEMBER CONDUCTINGLY ENGAGES SAID CONTACT SURFACES; RETURN OF SAID ACTUATOR TO A NEUTRAL POSITION PERMITTING THE BEAMS TO REENTER THE RADIAL DEPRESSION AND RETURN THE ROTOR TO NONCONTACT POSITION; THE RESISTANCE OF SAID BEAMS TO DEFLECTION FROM THEIR NEUTRAL POSITION SERVING TO HOLD THE ROTOR IN NEUTRAL, NON-CONTACT POSITION, AND PRESSURAL ENGAGEMENT OF THE INNER ENDS OF THE DEFLECTED BEAMS WITH THE BEAMDEFLECTING SURFACE OF THE ACTUATOR SERVING TO HOLD THE ROTOR IN CONTACT POSITION.
