Abstract
PURPOSE:To simplify the operation, by interlocking the off-hook of a handset and the operation of a speaker switch with each other. CONSTITUTION:In case of outgoing, when a speaker switch 6 is depressed under a waiting state 15, the inversion output of a flip flop 11 becomes ''L'', and a lamp 7 is lit to operate a relay R. A telephone circuit 12 is connected to the line through a terminal 14 by closing of a contact r1 of the relay R, and a contact r2 is switched to an amplifier 13, and thus, a speaker receiving state 16 is set. When a handset 5 is hooked off, a hook switch HS1 is closed, and an HS2 is switched, and the flip flop 11 is reset to make the relay R unoperated, and thus, a handset call state 17 is set.
