Switching device for meters of an automatic meter reading system
First Claim
1. A SWITCHING DEVICE FOR USE IN METERS OF AN AUTOMATIC METER READING SYSTEM COMPRISING, IN COMBINATION, AN ELONGATED REED SWITCH, A PAIR OF NORMALLY OPEN MAGNETIC, OVERLAPPING, CONTACT MEMBERS MOUNTED IN OPPOSITE ENDS OF SAID SWITCH, AN ELECTRICAL LEAD CONNECTED TO EACH OF SAID CONTACT MEMBERS, A ROTATABLE ELONGATED MAGNET MAGNETIZED ALONG ITS LENGTH, MEANS ROTATABLY MOUNTING SAID MAGNET WITH ITS AXIS OF ROTATION SUBSTANTIALLY AT THE POINT OF OVERLAP OF SAID CONTACT MEMBERS, MEANS TO ROTATE SAID MAGNET ABOUT SAID REED SWITCH WHEREBY WHEN SAID MAGNET IS SUBSTANTIALLY PARALLEL TO SAID REED SWITCH SAID OVERLAPPING CONTACT MEMBERS ARE CLOSED AND WHEN SAID MAGNET IS SUBSTANTIALLY CROSSWISE TO SAID REED SWITCH SAID OVERLAPPING CONTACT MEMBERS ARE OPEN, AND A MAGNETIC COMPENSATING MEANS ON SAID REED SWITCH TO PROVIDE AN ADDITIONAL PATH FOR THE MAGNETIC FLUX OF SAID MAGNET TO THEREBY DECREASE THE TORQUE REQUIRED TO MOVE SAID MAGNET FROM THE PARALLEL POSITION WITH RESPECT TO SAID REED SWITCH.
