ABSTRACT:
The present invention discloses a mechanical pushbutton type pulse generating switch for use in a telephone set comprising, in general, pulse generating switch units, a push-break return-make switch unit, and an end pulse generating switch unit. The pulse generating switch unit has a common normally closed contact attached to one side surface of an operating or push-button shaft having a polygonal cross sectional configuration and a plurality of make-break contact groups attached to the remaining side surfaces of the operating shaft and brushes or wipers disposed in opposed relation with and for contact with the common and make-break contacts respectively. The push-break return-make switch unit circuit is connected in series to a parallel circuit consisting of the pulse generating switch unit circuit and the end pulse generating switch unit circuit. The push-break return-make switch unit is so arranged that the number pulses may be generated only in the return stroke of the operating shaft after the latter has been completely depressed, and the end pulse is generated immediately before the operating shaft is returned to its initial or inoperative position and immediately before the push-break return-make switch unit is opened.
