The bridging element (210) comprises a contact surface (260), which is arranged to be coupled to the first and second contacts (270, 280) of the switch mechanism. The bridging element (210) further comprises two or more bridging formations (220) located on the contact surface (260) such that, when the bridging element (210) is in the closed condition, at least one bridging formation (220) forms an electrical contact with one of the first or second contacts (270, 280). The bridging formations (220) are in the form of dimples or protrusions and the switch mechanism comprises a dome switch. The electronic device may be a mobile telephone handset, personal computer or a domestic, commercial or industrial appliance.</p> |
