Electric position sensor

Claim 1

AN ELECTRIC POSITION SENSOR OF THE VARIABLE RESISTANCE TYPE COMPRISING A SUPPORT MEMBER HAVING A LONGITUDINAL AXIS, A PLURALITY OF MAGNETICALLY ACTUATED SWITCHES, EACH OF SAID SWITCHES COMPRISING AN ELONGATED HERMETICALLY SEALED CASING HOUSING A PAIR OF NORMALLY OPEN SWITCH CONTACTS AND MEANS MAGNETICALLY ACTUATING SAID SWITCH CONTACTS TO A CLOSED POSITION IN RESPONSE TO A MAGNETIC FIELD OF PREDETERMINED STRENGTH PASSING THROUGH SAID SWITCH CASING IN THE DIRECTION OF THE LONGITUDINAL AXIS THEREOF, MEANS MOUNTING SAID SWITCHES ON SAID SUPPORT MEMBER SO THAT THEY ARE PROGRESSIVELY DISPLACED IN THE DIRECTION OF HE LONGITUDINAL AXIS OF SAID SUPPORT MEMBER WITH THE LONGITUDINAL AXIS OF THE CASING OF EACH SWITCH EXTENDING IN DIRECTION PARALLEL TO THE LONGITUDINAL AIXS OF SAID SUPPORT MEMBER, A PLURALITY OF RESISTORS ELECTRICALLY CONNECTED IN SERIESCIRCUIT RELATION TO PROVIDE TERMINAL CONNECTIONS AND A PLURALITY OF INTERMEDIATE CONNECTIONS BETWEEN THE RESISTORS, MEANS ELECTRICALLY CONNECTING ONE OF THE CONTACTS OF EACH OF SAID SWICHES TO A COMMON CONDUCTOR, MEANS ELECTRICALLY CONNECTING THE OTHER CONTACT OF EACH OF SID SWITCHES TO DIFFERENT ONES OF SAID INTERMEDIATE AND TERMINAL CONNECTIONS SO THAT THE ELECTRICAL RESISTANCE BETWEEN SAID COMMON CONDUCTOR AND ONE OF SAID
