摘要： An electrical switch comprises at least one fixed contact which is engageable by a movable contact contained on a first arm portion of a movable contact member which also has a second arm portion which is disposed at an angle to the first arm portion. An actuating member is engageable with the movable contact member and is displaceable over the second arm portion to engage the first arm portion and to pivot it in a direction to move the movable contact to engage the fixed contact. First spring means bias the actuating member in a direction toward engagement with the movable contact member and during the movement of the movable contact member the second arm portion is moved in a direction opposite to the direction of the first arm portion to force the first spring means to increase the biasing force thereof. In the closed position of the contact the first spring means may in one embodiment be increased in biasing force and in another embodiment be maintained at the same biasing force as its initial position. A second spring means acts in a direction to return the actuating member to a non-actuated position.
摘要翻译：电开关包括至少一个固定触点，该固定触点可容纳在可移动触头部件的第一臂部分上的可动触头，该可动触头还具有与第一臂部分成角度设置的第二臂部分。致动构件可与可动接触构件接合，并且可在第二臂部分上移动以接合第一臂部分并使其枢轴转动以移动可动触头以接合固定触点。第一弹簧意味着使致动构件朝向与可动接触构件接合的方向偏压，并且在可动接触构件的运动期间，第二臂部分沿与第一臂部分的方向相反的方向移动，以迫使第一弹簧装置以增加其偏压力。在接触的关闭位置中，在一个实施例中，第一弹簧装置可以增加偏置力，而在另一个实施例中，第一弹簧装置可以保持与其初始位置相同的偏置力。第二弹簧装置沿着将致动构件返回到非致动位置的方向起作用。
