Abstract

PURPOSE:To handle a telephone set with a single hand, by connecting switches that open and close according to a pick-up and put-down of a telephone receiver with a relay switch which words with a push-button in parallel. CONSTITUTION:The relay switches 14, 15 and 18 close for a certain time set by a timer 12 when a push-button 11 provided with spring is pushed. Thus a telephone set is connected to a central office. Then a timer 12 is reset by the electric signal supplied from a mobile stopper 16 that is provided newly at the stopper position of a dial. Furthermore a detecting circuit B is connected to terminals 3 and 4 of the central office side with a closure of the relay swtich 18. Thus either a calling mode or a busy mode can be made known without picking up the telephone receiver.
