Abstract
A magnet switch or selector for selecting the functions of a multiple function electronic circuit device in a housing. A plurality of reed switches are incorporated into the electronic circuit device for switching on and off respectively the multiple functions. The reed switches are arranged in a sequence in proximity to a horizontal surface of the housing. An elongate sliding groove or sliding channel is formed in the horizontal surface of the housing in proximity to the reed switches, and the channel is oriented and arranged in a configuration along the sequence of reed switches. A magnet element having a cross-sectional profile substantially conforming to the cross-sectional profile of the channel is seated in the channel for restrained and controlled sliding motion back and forth along the sliding channel. The magnet element is magnetized with magnetic lines of force extending into the housing below the magnet element when the magnet element is seated in the sliding channel for selected magnetic actuation of the reed switches according to the position of the magnet element in the sliding channel. The magnet selector may also have a plurality of sliding channels and a plurality of magnet elements seated in respective sliding channels.
