    Abstract: A condition-responsive snap action electric switch mechanism, for use with a room air conditioner for instance, includes an operator which moves between extreme positions in response to a bellows. The bellows pressure increases and decreases in response to changes in temperature of the air passing over the evaporator. The switch also includes a first set of contacts to control energization of the compressor and a second set of contacts, including a snap-acting arm, to control energization of the evaporator and condenser fan motor. The operator includes an operating arm having a first portion which opens and closes the first set of contacts as the operator moves through a first, snap action, increment of travel between its extreme positions. The operating arm also includes a second portion which effects snap action of the snap-acting arm to open and close the second set of contacts as the operator moves through a second increment of travel separate from the first increment of movement.

    Abstract translation: 例如，与室内空调一起使用的条件响应快速动作电动开关机构包括响应于波纹管在极限位置之间移动的操作器。 响应于通过蒸发器的空气的温度变化，波纹管压力增加和减小。 该开关还包括用于控制压缩机通电的第一组触点和包括卡合臂的第二组触点，以控制蒸发器和冷凝器风扇马达的通电。 操作者包括操作臂，操作臂具有第一部分，当操作者在其极限位置之间移动通过第一快速动作时行程增加，该第一部分打开和关闭第一组触点。 操作臂还包括第二部分，当操作者通过与第一移动增量分开的第二行程增加时，该第二部分实现弹力臂的打击和闭合的第二组接触。
