ABSTRACT An electric strip switch for safety and similar application comprising a pair of metal strips 1, 2 of stainless steel separated, except at their overhanging long edges, by a foam tape 3. Electrical connections (not shown) are taken from the strips 1, 2 to provide a normally open switch. The switch is actuated by means of a U-section strip 17 of foam material whose legs 19, 20 touch, or nearly touch the overhanging edges of strips 1, 2. Pressure applied in any one of the three directions P1, P2 or P3 will cause the legs to cause one or both of the overhanging edges to contact, thus closing the switch.
