Abstract
A switching device (220) comprises a solenoid actuator (224) and an inlet terminal (224) attached to a first bus-bar (246). Mounted on the bus-bar is a flexible switch blade (236) operable by the actuator and having a movable contact (240) at its free end. An outlet terminal (254) is connected by a second bus-bar (250) to a fixed contact (242) of the contact pair, the arrangement being such that in use an electrodynamic force is produced at least between the blade (236) and the first bus-bar (246) which tends to maintain the contacts (240, 242) in engagement.
