Abstract

1,027,976. Selective signalling. A. I. ARMANDO. May 20, 1964 [Dec. 12, 1963], No. 20760/64. Heading G4H. [Also in Division G1] The reading of a tachometer is indicated remotely by means of a rotary switch having a wiper and plurality of spaced contacts each connected to an individual indicating lamp and the arrangement is characterized in that the wiper is sufficiently wide to bridge the gap between adjacent contacts whereby during the transition from a speed corresponding to one lamp to a speed corresponding to the adjacent lamp, both lamps are energized.
