Summary:An electrical switch comprising a body supporting a first electrical contact. A second electrical contact is spaced from the first contact and a switching element is interposed between the first and second contacts. The switching element is formed from flexible, electrically insulating material and contains discrete particles of electrically conducting material which are brought into contact to define conductive paths through the element when the element is compressed beyond a predetermined amount. Slidably mounted in the body is an operating member, and the operating member and the second contact include a cam arrangement whereby movement of the operating member in one direction causes movement of the second contact towards the first contact to compress the element. The element is compressed by this movement from a rest state wherein the element electrically insulates the first and second contacts from one another, beyond the predetermined amount so that the element electrically interconnects the first and second contacts.
