<p>A switch element for surface mounting onto a printed circuit board which has a bearer element (2) and a contact element (1). Both the bearer element and the contact element are formed from an electrically conductive material and the contact element being formed from a resilient material. The bearer element and the contact element can be of an integral construction or are separate components assembled together. By this construction the bearer element comprises a peripheral retainer for the contact element. In one arrangement the bearer element has an inwardly facing C-shaped cross sectional shape to provide a recess to act as a peripheral retainer for the contact element by receiving at least a portion of the rim of the contact element in the C-shaped member recess.</p> |
