Magnetically controlled switch

Claim 1

A SWITCH DEVICE OF THE CHARACTER DESCRIBED COMPRISING A CASING, A WALL OF THE CASING HAVING AN ELONGATED APERTURE THEREIN, A U-SHAPED BRACKET IN SAID CASING, A MERCURY SWITCH SUPPORTED IN SAID BRACKET, SAID SWITCH HAVING A SPRING ACTUATED CONTACT CONTROLLING AN ELECTRIC CIRCUIT BY MOVEMENT INTO AND OUT OF ENGAGEMENT WITH THE MERCURY OF SAID SWITCH, AN ARMATURE ON SAID SPRING CONTACT, AN ELEMENT PIVOTALLY MOUNTED FOR FREE SWINGING MOVEMENT OF THE CASING TOWARD AND FROM THE ARMATURE OF SAID SPRING CONTACT, SAID ELEMENT HAVING A SHORT END SUPPORTING A MAGNET IN POSITION ADJACENT AND REGISTERING WITH SAID ARMATURE IN SUPPORT OF THE SPRING CONTACT IN PREDETERMINED CIRCUIT CONTROLLING POSITION IN THE NORMAL POSITION OF SAID ELEMENT, SAID ELEMENT HAVING A LONG END WHICH, IN THE NORMAL POSITION OF SAID ELEMENT, PROJECTS THROUGH THE ELONGATED APERTURE IN SAID WALL OF THE CASING AND ADAPTED TO BE ACTUATED THROUGH A SUITABLE MEDIUM MOVABLE OVER THE SURFACE OF SAID WALL OF THE CASING IN ONE OF TWO DIRECTIONS IN MOVEMENT OF THE MAGNET AWAY FROM THE ARMATURE OF SAID SPRING CONTACT TO A DEGREE RELEASING THE SPRING CONTACT FOR PREDETERMINED CONTROL OF THE CIRCUIT IN WHICH THE SPRING CONTACT IS ARRANGED, THE ELONGATED APERTURE IN THE WALL OF SAID CASING BEING SUCH AS TO PERMIT MOVEMENT OF THE LONG END OF SAID ELEMENT TO POSITION WITHIN BOUNDARIES OF THE CASING IN ACTUATION OF SAID LONG END OF THE ELEMENT BY SAID MEDIUM IN SAID ONE DIRECTION, A MANUALLY ADJUSTABLE DIRECTION CONTROL STOP IN SAID CASING, AND RELEASE OF THE LONG ARM OF SAID ELEMENT BY SAID MEDIUM PROVIDING AUTOMATIC RETURN OF THE ARM TO NORMAL POSITION ENGAGING SAID STOP BY ACTION OF SAID MAGNET.
