<p>A linear motion snap-action mechanism includes a reference frame having a pair of carrier slots. First and second spring-loaded detent pins are respectively disposed and movably mounted in the carrier slots. An input arm is slidably mounted about the frame and includes two spaced-apart ramp members, wherein each ramp member engages and moves one of the pins when the input arm is in a corresponding position. An output arm is also slidably mounted about the frame and includes two spaced-apart detent slots, each slot receiving one of the detent pins when the output arm is in a corresponding position. A storage spring is constrained between the input and output arms and is compressed by longitudinally translating the input arm away from the output arm until one of the ramp members moves one of the spring-loaded pins out from a detent slot of the output arm at which time the spring snaps the output arm toward the input arm.</p> |
