摘要： A modular electrical switch provides a wiping or shearing action upon closing and opening thereof. A contact carrier disposed within a housing linearly carries a movable contact into engagement with a stationary contact. The contact carrier is guided by movable slide plates disposed on either side thereof and movable along with the contact carrier as a contact assembly. The guide plates also provide pivot recesses for pivot bosses of the contact carrier. The contact carrier is constrained to linear motion up to the point of contact between the movable contact and the stationary contact by a cam trace in the housing. After contact between the movable contact and the stationary contact, the contact carrier reaches a pocket defined by the cam trace, ceases linear movement and upwardly pivots to provide a wiping action between the movable contact and the stationary contact. Immediately upon reversed, pivoting and linear motion of the contact carrier a shearing action is provided between the movable contact and the stationary contact. A plurality of such modular switches are utilized in a freight elevator interlock system for regulating the opening and closing of the various doors and carriage of the freight elevator. A common sliding actuator controls the modular switches regardless of the orientation of the respective switches within the housing.
摘要翻译：模块化电气开关在其闭合和打开时提供擦拭或剪切动作。设置在壳体内的接触载体线性地携带可动触头与固定触点接合。接触托架由设置在其任一侧上的可动滑板引导，并可作为接触组件与接触托架一起移动。引导板还提供用于接触托架的枢轴凸起部的枢转凹部。接触载体通过壳体中的凸轮轨迹被约束到直到活动点到可动触头和固定触点之间的接触点。在可动触点和固定触点接触之后，触点载体到达由凸轮轨迹限定的凹穴，停止线性运动并向上枢转以在可动触头和固定触点之间提供擦拭动作。立即在接触载体的反转，枢转和线性运动之后，在可动触点和固定触头之间提供剪切动作。在货运电梯互锁系统中使用多个这样的模块化开关，用于调节货梯的各种门和托架的打开和关闭。常规的滑动执行器控制模块化开关，而不管壳体内相应开关的方向如何。
