Abstract

Encapsulated reed switch 10 is positively transferred by pivoted flux conductor 11. The latter is positioned adjacent permanent magnet 12 and is oppositely positioned by spring 13 and input force 14. In the position shown, flux from magnet 12 is conducted through conductor 11 and reeds 15 and 16 of switch 10 causing such reeds to close. Removal of input force 14 permits spring 13 to pivot flux conductor 11 clockwise to a position where flux is directed only through reed 16, thus isolating reed 15 from the magnetic field and causing the switch to open.
