Abstract
An improved switch mechanism for controlling the actuation of a plurality of electrical switches by means of tablets of a musical instrument, such as an organ. The mechanism permits a plurality of tablets to be depressed simultaneously and releasably retained in the depressed position so as to maintain a selected actuation of switches such as for providing selected voicing circuits in an organ. The mechanism is arranged to cause an automatic release of any previously depressed tablet as an incident of the user depressing subsequently one or more tablets to the switch actuating position. The tablets may be biased to the switch releasing position with the mechanism permitting the biasing structure to return the tablets to the switch releasing position as an incident of such further tablet depression.
