A telephone handset comprises two parts, one containing the mouthpiece and the other the earpiece, hinged together.

A hook switch 4 and a dial 5 are mounted in body part 11 while a support magnet 8 is mounted in body body part 111. The handset may also contain a bell or buzzer and may be connected to the telephone network by wires or by a radio link. Magnet 8 co-operates with an iron plate 9 attached to a wall M to support the handset when not in use. When body part 11 is gripped and the handset removed from the wall and inverted, body part 111 pivots into line with part 11 and operates hook switch 4. In other embodiments the hand set may be hung from a hook on a wall, Fig. 5 (not shown), or placed flat, Fig. 4 (not shown), or stood on its hinged ends on a horizontal surface, Fig. 3 (not shown). The handset may also be constructed in three parts hinged together, Fig. 7 (not shown). The handset may be constructed with the dial coaxial with the earpiece, so that when folded with the mouthpiece and earpiece towards one another, the dial is on the outside of the handset, Figs. 8 to 10 (not shown).
