Abstract: The connection arrangement according to the present invention is primarily intended to connect a loudspeaking device instead of the normal lowspeaking device (receiver in the handset) in a telephone instrument of the "DIAVOX" type. The arrangement includes an extra push button (1) mounted on a circuit card (22) in the instrument. A cam shaft relay (4, 5), known per se, is mounted near the push button support (1e) and on the card. The cam shaft relay is provided with a control member (5) having a first position which corresponds to the rest state of the instrument. Under the influence of the hook switch plunger (18) of the instrument, the control member (5) can be set to a second position corresponding to the lowspeaking state. The push button is provided with tipping element (2) which, when the button is depressed, actuates the control member (5) to set it to a third position corresponding to the loudspeaking state of the instrument.

Abstract: A switch actuating device for a telephone instrument of the one piece type comprising actuating means protruding through the base portion of the instrument for actuating the off-on switch when the instrument is removed from or put on a table surface. Said projecting actuating means comprises along a peripheral outline of said base portion distributed parts, each of which cooperates with an element which actuates the contact springs of the switch. Said element is symmetrically constructed and comprises two links and two arms. The links are turnably mounted in bearings, are spring actuated and are at their ends actuated by the said actuating means.
