    摘要： 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.

    摘要： A switch (10) for providing a safety function when its main contacts are fused or stuck together in the "ON" position, comprising a housing (16) containing a pair of main contacts (42, 54), one being designated an ON contact, and the other main contact being carried by a movable switch arm (50) in the housing (16). This switch arm (50) has a first end which carries the movable main contact (54) and a second end, and spring means (56) mechanically coupled to the movable switch arm (50) normally bias the movable main contact (54) toward open position away from engagement with the ON contact. Switch operating means including movable actuator means (78) overcome the biasing force of the spring means (56) for moving the movable main contact (54) to closed position into engagement with the ON main contact. There are auxiliary safety contact means (60) within the switch housing for completing a safety circuit and/or for deenergizing the main circuit in response to abnormal movement of the movable switch arm (50) when the actuator means (78) is moved to OFF position, but the movable main contact (54) remains fused or stuck to the ON main contact.

    摘要： An electric quick-break switch with forced opening of the contacts comprises a fixed part (10) containing two pairs of fixed contacts (12, 13; 14, 15) and a movable part comprising an operating button (17) where to two quick-release toggle springs (18) are pivoted which retain a movable contact bodge (16), wherein, below the two points where said toggle springs (18) are pivoted, two semicylindrical seats (22) are provided which accomodate in hinged relationship a first end or inside end each of two L-shaped levers (20) resting each in sliding relationship with a first leg of the "L" on a raised portion (21) rigid with the fixed part of the switch, provided with two circular projections (24) at the elbow of the "L" adapted each for sliding against a sidewall of cylindncal seats (23) on said fixed part and with outside ends or dual lugs (25) moving along two symmetrical arcuate paths with respect to said operating button (17). In the event of a malfunction of the movable contact bridge (16), said levers will interfere with the same to force the normally closed contacts open and the normally open contacts of the switch closed.
