The switching mechanism (14) is mounted on the block (12) holding the load contacts. The insulated contact carrying lever (18) is perpendicular to the plate (16,17) which carries the contacts, and is separated from them by side walls. Each contact arm (19) carries a contact, and the arm is connected by a flexible link (20) to its cable terminal (21) of the switch. Each contact arm is arranged in the same way. Each contact arm has an individual spring which, when the switch is closed, provides the required contact pressure. In the open position the contact arm is at an angle to the vertical, and the spring, typically a coil spring, has its axis normal to the contact arm.
