摘要：
A latch assembly configured to attach to a door includes one of a knob and a lever. The latch assembly further includes a latch extending from the door. A spindle is rotatable from a first position to a second position to move the latch from an extended position to a retracted position. A first biasing member is selectively operable to bias the spindle toward the first position. A second biasing member is selectively operable to bias the spindle toward the first position. An actuator is movable between a knob position in which only one of the first biasing member and the second biasing member biases the spindle toward the first position and a lever position in which both the first biasing member and the second biasing member cooperate to bias the spindle toward the first position.
摘要（中）：
构造成附接到门的闩锁组件包括旋钮和杆中的一个。 闩锁组件还包括从门延伸的闩锁。 主轴可以从第一位置旋转到第二位置，以将闩锁从延伸位置移动到缩回位置。 选择性地操作第一偏置构件以将主轴偏压到第一位置。 第二偏置构件可选择性地可操作以将主轴偏压到第一位置。 致动器可在其中仅第一偏置构件和第二偏置构件中的仅一个将主轴朝向第一位置偏压的把手位置和杆位置之间移动，杆位置中第一偏置构件和第二偏置构件两者协作以使主轴 朝着第一位。
