Abstract
An electrical switch having a casing, at least two fixed contacts and a corresponding moving contact. The moving contact has two parts contactable with the fixed contacts respectively thereby closing the switch. An operating member is supported for movement for moving the moving contact to close the switch. A spring acts upon the moving contact such that its two parts are inclined at an acute angle relative to the fixed contacts, with at least one of the parts being spaced apart from the corresponding fixed contact while the switch is open. The moving contact is movable such that said at least one or both of its parts comes or come into contact with the corresponding fixed contact or contacts against the action of the spring. In particular, the moving contact is movable against the action of the spring to have its two parts turning through said acute angle until both parts are in contact with the corresponding fixed contacts.
