    • A switch having at least one pair of fixed contacts and at least one pair of movable contacts adapted to cooperate with these fixed contacts, the movable contacts are connected with each other by fuse means and they are supported together with these fuse means by a supporting plate which is movable between a closed position nearest to the fixed contacts and an open position farthest to the said fixed contacts. When at the open position the supporting plate may be turned on itself through 180* so as to bring the fuse means on what is now its outer side, where they are separated from the live parts of the switch by the supporting plate itself. The switch may then be brought to an ineffective closed position for which the supporting plate wholly covers the fixed contacts and forms a closure for the open side of the switch casing. The fuse means of each pair are preferably in the form of a removable fuse cartridge having end blades which constitute the movable contacts.
    • 开关具有至少一对固定触头和至少一对适于与这些固定触点协作的可移动触点,可动触头通过熔断装置相互连接,并且它们通过支撑板与这些熔断装置一起支撑在一起 其可在最靠近固定触点的关闭位置和最远离所述固定触点的打开位置之间移动。 当处于打开位置时,支撑板可以自身转过180度,以便使保险丝装置在现在的外侧,在那里它们通过支撑板本身与开关的带电部分分离。 然后可以将开关置于无效的关闭位置,支撑板完全覆盖固定触头并形成用于开关壳体的开口侧的封闭件。
