Abstract

1,137,991. Musical instrument keyboards. WURLITZER CO. 17 May, 1966 [24 May, 1965], No. 21931/66. Heading G5J. [Also in Division H1] A keyboard for an electronic organ comprises keys each carrying a magnet which in response to actuation of the key magnetically operates a corresponding switch contact. As described the keys 38 of a foot clavier each carry a plate like magnet 92 secured to one end. A dry reed switch 76 is mounted adjacent each key. Each magnet is magnetized in a direction along the length of its associated key so that when this key is in the raised position as shown the contacts of the corresponding reed switch 76 act as like poles and repel each other thus opening the switch. The dry reed switches are sealed in glass envelopes which may contain an inert gas.
