MECHANICALLY ACTUATED ELECTRIC SWITCH ASSEMBLY

摘要

A highly reliable and readily serviceable electric switch is afforded by a simple and inexpensive 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 actuating means, the change in the magnetic field about the reeds actuates the magnetic reed switch contact elements. A minimum of mechanical wear is encountered, and the magnetic reed switch capsules are quickly and conveniently replaceable. A plurality of such magnetic reed capsules may be actuated by a single pair of tubular magnets. All of the reed switch elements may be activated substantially simultaneously or the capsules may be offset with respect to one another for actuating the various reed contact elements sequentially. Push button arrangements are described for keyboard applications.
