<p>An apparatus sets a telephone (10) to an on-hook state. The telephone (10) has a base (14) with at least one cavity (24) forming a cradle for a handset (12). The telephone (10) also has a handset (12) with an operative surface (26) including a mouthpiece microphone and an earpiece speaker. A first surface (27) of the handset is opposite to the operative surface (26). The apparatus includes a first arm (36) having a surface, and the first arm (36) responds to the surface being pressed by a portion of the handset being positioned in the base. The first arm (36) moves to actuate an on-hook switch (73) to set the telephone to the on-hook state. The surface of the handset which presses the first arm is the operative surface or the first surface. The first arm (36) responds to the handset having the operative surface facing away from the base. The first arm (36) also responds to the handset being positioned entirely out of the cradle by extending from a first slot (68) in the base. With a portion of the handest being positioned in the cradle, the first arm (36) is moved by the portion to be retracted through the first slot into the base. A cooperative arm (40) is pivotally coupled to the first arm, with retraction of the arm (36) into the base causing the cooperative arm (40) to extend through a cooperative arm slot (72) to engage the handset to maintain the first arm in a retracted position in the base.</p> |
