Abstract (en)
[origin: EP0214848A2] An electrical isolator switch has a moving contact member (20) as a link bridging between spaced stationary contacts (22,24) in its make position. the moving contact member (20) has associated means (28) biasing it towards its make position. Operation of associated break-forcing means (18) results in preference for the moving contact member (20) to break its contact (24B) with one of the stationary contacts (24A of 24) rather than the other (22A of 22), but the other contact (22A,22B) will break if the one contact (24A,24B) is reluctant to break. The break-forcing means has a link (18) pivotted to a switch dolly (14) and retained on the moving contact member for positive action.
