ABSTRACT:
Methods and systems for actuating a negative rate switch. A negative rate switch comprising a plunger and a resilient actuator thereof can be provided, wherein a highest plunger force occurs at a free position and a lowest plunger force occurs at a full over travel position. The negative rate switch can be configured such that when the resilient actuator provides resilient actuating force to overcome a free position force associated with the free position, the plunger moves without interruption through a total range of travel thereof and when the resilient actuating force drops slightly below a full over-travel plunger force associated with the full over travel position, the negative rate switch overcomes the resilient actuating force to return the plunger to the free position thereof without interruption.
