摘要：
An electrical switch (62) has a substrate (64) with at least one pair of spaced switch contacts (82, 84) arranged to be shorted by an electrically conductive armature (78). The armature (78) defines a central axis with first and second portion on either side of the axis which portions terminate at first and second edges. The armature (78) is normally held spaced from the contacts (82, 84) by magnetic attraction to a coupler layer (70) disposed in spaced relation to the substrate (64). The armature (78) is movable by an actuating force to engagement with the substrate (64). The armature (78) separates from the coupler layer (70) by a double pivoting motion. An actuating force applied to the armature (78) remote from its central axis causes one edge of the armature (78) nearest the actuating force to break away from the coupler layer (70). The armature (78) then pivots about the opposite edge of the armature (78) until the one edge bottoms on the substrate (64). This is followed by the opposite edge of the armature (78) breaking away from the coupler layer (70) and pivoting about the one edge until the opposite edge bottoms on the substrate (64).
摘要（中）：
电开关（62）具有衬底（64），其中至少一对间隔开的开关触点（82,84）被布置成由导电电枢（78）短路。 电枢（78）限定中心轴线，其中在轴的任一侧的第一和第二部分，这些部分终止于第一和第二边缘。 电枢（78）通常通过与设置成与衬底（64）间隔开的耦合器层（70）的磁吸引而与触点（82,84）间隔开。 电枢（78）可通过致动力移动以与基底（64）接合。 电枢（78）通过双重枢转运动与耦合器层（70）分离。 远离其中心轴线施加到电枢（78）的致动力导致最靠近致动力的电枢（78）的一个边缘脱离耦合器层（70）。 电枢（78）然后绕电枢（78）的相对边缘枢转，直到一个边缘在基板（64）上。 之后是电枢（78）的相对边缘脱离耦合器层（70）并围绕一个边缘枢转直到基板（64）上的相对边缘底部。
