Abstract

701,916. Keyboard switches. WALKER & SONS, Ltd., J. W., and SYMONDSON, A. H. April 30, 1952 [Feb. 1, 1951], No. 2524/51. Class 38(5) [Also in Group XXXVIII] In a switching arrangement for an organ, particularly for setting stop combinations and pistons ', each switch has three positions and comprises a slidable contact 1 which co-operates with three fixed contacts 6, 9 and 7 in such a manner that it always engages the centre contact 9 and forms a bridge between contact 9 and 6 or 7 in each end position. The contact 1 is actuated by a rocking member or key 11 having a spring pressed plunger 8 engaging the contact 1. Frictionally-mounted telltale devices 16 are mounted alongside the switch keys 11 so that if the keys have to be moved into new positions, the devices 16 can be left to indicate the old positions, enabling the latter to be readily restored.
