    • A common conductor unit for a contact switch includes a conductor body and a movable contact arm. The conductor body includes a U-shaped mounting unit that has upright first and second arm mounting portions and an elongated horizontal connecting portion which interconnects lower end edges of the arm mounting portions. Each of the arm mounting portions has one side which is opposite to the other one of the arm mounting portions and which is formed with a respective horizontal retaining groove. The contact arm is formed as an elongated plate and has a first end portion and a second end portion which is provided with a spring extension unit that extends toward the first end portion. One of the mounting unit and the contact arm is formed with a longitudinal opening to permit extension of the other one of the mounting unit and the contact arm when the contact arm is moved upwardly relative to the conductor body. The first end portion of the contact arm engages the retaining groove on the first arm mounting portion. The spring extension unit engages the retaining groove on the second arm mounting portion and biases the contact arm upwardly. The upper end edge of the second arm mounting portion is formed with a retaining unit to limit upward movement of the contact arm.
    • 用于接触开关的公共导体单元包括导体本体和可动接触臂。 导体主体包括具有直立的第一和第二臂安装部分的U形安装单元和互连臂安装部分的下端边缘的细长的水平连接部分。 每个臂安装部分具有与另一个臂安装部分相对的一侧,并且形成有相应的水平保持槽。 接触臂形成为细长板,并且具有第一端部和第二端部,该第二端部设置有朝向第一端部延伸的弹簧延伸单元。 安装单元和接触臂中的一个形成有纵向开口,以允许当接触臂相对于导体主体向上移动时,安装单元和接触臂中的另一个延伸。 接触臂的第一端部与第一臂安装部分上的保持槽接合。 弹簧延伸单元接合第二臂安装部分上的保持槽并向上偏压接触臂。 第二臂安装部的上端边缘形成有用于限制接触臂向上移动的保持单元。

    • A contact switch assembly includes a first conductor body which has a leg portion and a U-shaped mounting unit with upward first and second mounting arms and a connecting portion that interconnects the first and second mounting arms. The first and second mounting arms have transverse retaining grooves at opposing outer sides thereof. A movable contact arm includes an elongated contact plate which has a longitudinal opening and which is sleeved around the first and second mounting arms via the opening. The contact plate further has first and second inner edges at two longitudinally opposing ends of the opening. The first inner edge engages the retaining groove of the first mounting arm. A curved spring plate has a first end engaging the retaining groove of the second mounting arm, and a second end engaging the second inner edge so as to bias the second inner edge upward. The second end of the spring plate has a first portion for abutting against a bottom surface of the contact plate, and a second portion for abutting against a top surface of the contact plate, thereby preventing release of the second end from the second inner edge.
    • 接触开关组件包括具有腿部的第一导体本体和具有向上的第一和第二安装臂的U形安装单元和将第一和第二安装臂互连的连接部分。 第一和第二安装臂在其相对的外侧具有横向保持槽。 可移动接触臂包括具有纵向开口的细长接触板,并且经由开口围绕第一和第二安装臂套管。 接触板还具有在开口的两个纵向相对端处的第一和第二内边缘。 第一内缘接合第一安装臂的保持槽。 弯曲的弹簧板具有接合第二安装臂的保持槽的第一端和与第二内边缘接合以便将第二内边缘向上偏压的第二端。 弹簧板的第二端具有用于抵靠接触板的底表面的第一部分和用于抵靠接触板的顶表面的第二部分,从而防止第二端从第二内边缘的释放。
