Abstract

10,856. Norden, M. May 12. Signals, electric-lamp.-Relates to switches or switchboards having a number of contacts and detachable perforated cards so that any predetermined number or arrangement of contacts can be made for illuminating lamp signals. Figs. 1 and 4 show a construction of switch. A block f carrying a number of contact-pins h, adapted to engage contacts fitted on the base or plate 4 and connected to the lamps, is hinged at e. A card, Fig. 8, having perforations 30 is slipped in a groove 5, and only permits certain of the contact-pins h to engage the corresponding fixed contacts and thus to light certain lamps only. The main switch consists of bars a, b operated by the handle 16, and a spring i is placed between it and the contact-carrying plate f so that the main switch is closed after and opened before the contacts are made or broken by the pins h. The card may be provided with a detachable piece to be given to a driver, to call a carriage in leaving a theatre.
