Abstract

An electrical isolator switch having a moving contact member (20) in the form of a link bridging spaced stationary contacts (22, 24) in which the moving contact has a preference for breaking its electrical contact with one (24) of the stationary controls rather than the other (normal break action) but can be broken at the other, and wherein means (x) is provided to limit movement of the moving contact member away from said other stationary contact to force breaking at said one contact.
