Abstract: Two flat movable contact blades are mounted adjacent first ends thereof in spaced parallel relationship respectively on opposite sides of a flat stationary mounting blade for edgewise pivotal movement of their other end portions into and out of engagement respectively with opposite sides of a flat stationary contact blade aligned with the mounting blade. Threaded stud and nut clamping means are provided for automatically clamping the movable contact blades adjacent opposite ends respectively to the mounting blade and to the stationary contact blade after the movable contact blades reach a fully closed position. Cam means carried by the movable contact blades overcomes static friction and high magnetic forces to prevent welding of the blades in closed position upon flow of excessively high currents.

Abstract: A safety switch having a reciprocable cover sealing cam member operable by a cover sealing handle and having first interlock means preventing movement of the switch blade operating handle and switch blades to ON position when the cover is open or is closed but not sealed. A second interlock means is provided preventing operation of the cover sealing handle and cam member when the cover is open, thereby preventing defeat of the first interlock means by manipulation of the cover sealing handle.

Abstract translation: 一种安全开关，其具有可往复运动的盖密封凸轮件，所述往复式盖密封凸轮件可由盖密封手柄操作并且具有第一互锁装置，以防止当盖打开或关闭但未被密封时开关刀片操作手柄和开关刀片移动到ON位置。 提供第二联锁装置，当盖打开时防止盖密封手柄和凸轮构件的操作，从而通过操纵盖密封手柄来防止第一互锁装置的失效。
