Abstract

An electric switch is provided by a magnetic reed switch capsule and a pair of tubular magnets slidably arranged over the capsule. Like magnetic poles on the annular faces adjacent each other hold the magnets apart, until they are brought together by mechanical switch actuating means. When brought together by the actuator, the change in the magnetic field about the reeds actuates the magnetic reed switch contact elements.

Mechanically Actuated Electric Switch

An electric switch is provided by a magnetic reed switch capsule and a pair of tubular magnets slidably arranged over the capsule. Like magnetic poles on the annular faces adjacent each other hold the magnets apart, until they are brought together by mechanical switch actuating means. When brought together by the actuator, the change in the magnetic field about the reeds actuates the magnetic reed switch contact elements.

A pair of binding posts 68 are arranged on circuit board 36'. Leads 46' and 48' are held in place by tightening screws 69. A bifurcated nonmagnetic finger 30' is for moving magnet 62. Support post 68 acts as a stop for magnet 64. When magnet 62 is moved toward magnet 64, the balance of the magnetic fields is changed. As magnet 62 approaches contacts 56 and 58, reeds 52 and 54 are bent toward each other closing contacts 56, 58. If magnet 62 is moved farther toward magnet 64, the contacts remain closed.
