The face plate 2 is provided with a groove 8 in its outer surface to define a push button and its flexibility in the region of the hole 12, is provided by a groove 4 in the face plate 2 and/or backing plate 10. An apertured PVC sheet 16 is positioned between the backing plate 10 and electrically insulating material 22 mounting the fixed contact 20. A movable contact ball 14 is positioned in the hole 12 which is lined with an insulating bush 13 and which may be inclined (Fig. 4, not shown). The face plate 2, backing plate 10 and contact ball 14 may be of stainless steel. In another embodiment (Fig. 5, riot shown) the fixed contact is defined by a pair of contact discs (53) positioned either side of a washer (54) and mounted on a printed circuit board (52). The switch may be mounted in a frame (70) (Fig. 7, not shown).
