ABSTRACT:
A MEMS resettable timer including a primary inertial element and at least one secondary inertial element, which includes a camming surface. When the secondary inertial element moves, its camming surface engages the camming surface of a locking element to remove it from the notch of a subsequent inertial element. When the primary inertial element is released for movement it activates a resetting arrangement to place the secondary inertial element back to the initial position and prevent further movement of the primary inertial element. The cycle is repeatable to commence some predetermined action.
