Abstract

2982. Hardegen, P. Feb. 13. Switches.-In an intercommunication telephone system, the contactarm is returned to the inoperative position by the weight of the receiver. In centralbattery installations, the contactarm b is connected with a cam i which displaces the spring k and effects the commutation of the poles of the battery. In the normal position as shown at station II, the microtelephone hangs on the arm b, keeping springs f, g in contact, while on removal of the instrument, the arm b is raised by the spring f until the latter contacts with the spring h. If the station I wishes to speak with station II, the microtelephone is removed and the arm b placed upon the line contacts for station I. This causes the cam i to move the spring k from contact l to contact m. On the instrument being hung up, the arm b. is brought back to the inoperative position, and the springs k, f return to their original positions.
