    • A switch assembly includes a housing having a plurality of terminals at one end and a push-button at the opposite end. An actuator mechanism is disposed in the housing and is connected with the push-button. The actuator mechanism is operable to move movable switch contacts relative to stationary switch contacts upon manual actuation of the push-button. A printed circuit extends between terminals at one end of the housing and the push-button. The printed circuit has a zig-zag portion disposed within the housing to accommodate movement of the push-button relative to the housing. The push-button is at least partially illuminated by light sources mounted on the printed circuit. The actuator mechanism includes a plurality of longitudinally extending actuator levers which are connected with the movable switch contacts and are pivotally connected with an actuator link. During actuation or release of the push-button, actuator link springs store energy which assists actuator lever springs in effecting rapid movement of the movable switch contacts relative to the stationary switch contacts.
    • 开关组件包括在一端具有多个端子的壳体和在相对端的按钮。 致动器机构设置在壳体中并与按钮连接。 致动器机构可操作以在手动致动按钮时相对于固定开关触点移动可移动开关触点。 印刷电路在壳体的一端和按钮之间的端子之间延伸。 印刷电路具有设置在壳体内的Z字形部分,以适应按钮相对于外壳的移动。 按钮至少部分地被安装在印刷电路上的光源所照明。 致动器机构包括多个纵向延伸的执行器杆,其与可移动开关触点连接并且与致动器连杆枢转地连接。 在按钮的致动或释放期间,致动器连杆弹簧存储能量,其帮助致动器杆弹簧实现可移动开关触点相对于固定开关触点的快速移动。
