Abstract
Abstract A telephone set, adaptable for either wall or desk top mounting, has an integral hookswitch and cup. The cup is at the rear of the telephone set, in the desk mounting mode, and at the top in the wall mounting mode. The cup receives the receiver end of the handset. The cup as a whole is pivoted and has a lever which acts on contact actuators of a switch. The cup is biased up, to an off hook position, being depressed by the handset to the on hook position.
