ORGAN KEYBOARD SWITCHING SYSTEM

A switch assembly operated by the keys of an electronic organ to connect different tone generators to the loudspeaker, which is simple and which minimizes mechanical and electrical noises during closing of the switches. The assembly includes a row of resilient switch members connected to the loudspeaker and positioned to be individually deflected up against a contact assembly. The contact assembly includes a a circuit board with numerous conductive pads arranged in a row above the row of switch members, a pair of insulating spacer strips extending along either side of the row of pads, and an intermediate strip of conductive plastic fastened to the spacer strips. When a key is depressed, a corresponding switch member is deflected upwardly to press a region of the plastic strip against a conductive pad.
