Claims

[Scope of utility model registration request]

Equipped with a hook switch and a self-locking switch for on-hook transmission, when going on-hook, the gravity of the handset pushes down the hook switch lever against the biasing force of its return spring, and the above-mentioned self-locking is performed via the hook switch lever. The release lever of the switch is operated and held in a standby state against the biasing force of the release spring, and when the hook switch lever returns to its original position when off-hook, the release lever is released from its hold and the release spring is activated. In a telephone set in which the above-mentioned release lever is actuated by a force, and thereby the outgoing state of the self-locking type switch is released, the above-mentioned hook switch lever and the release lever of the above-mentioned self-locking type switch are connected to each other, and the above-mentioned hook switch lever is released by off-hook. A telephone set characterized in that the telephone set is adapted to be engaged with each other even when
