The first arm moves to actuate an on-hook switch 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 responds to the handset having the operative surface facing away from the base. The first arm also responds to the handset being positioned entirely out of the cradle by extending from a first slot in the base. With a portion of the handset being positioned in the cradle, the first arm is moved by the portion to be retracted through the first slot into the base. A cooperative arm is pivotally coupled to the first arm, with retraction of the first arm into the base causing the cooperative arm to extend through a cooperative arm slot to engage the handset to maintain the first arm in a retracted position in the base. |
