A sliding electrical switch (10) for use in a garment (32) has two spaced elongate flexible surfaces (16, 18), at least one electrical contact on each surface (22a, b, c, d, e, f), and a slider (20) slidable along the surfaces to cause electrical connection between the contacts. There may be a number of spaced contacts (22a, b, c, d, e, f), the slider (20) acting as a selector switch; or there may be two continuous spaced contacts (96, 98), movement of the slider (90) providing a variation in resistance. The slider can be a bead (20) running on cords (16, 18) attached to the edges of spaced pieces of fabric (14, 18); or a buckle (42) sliding on a strip (50); or a zip fastener traveller (66), adjacent teeth (64) of the zip being electrically connected (68); or a bead (90) running on lengths (82, 84) of flexible tubing with internally conductive strips (96, 98).
