Generic miniature platforms providing either linear or angular displacement of a driven member with strokes up to 100 mm (for linear platforms) and 90° (for angular ones) with self-fixing said moving member at end positions without power consumption.

One of the applications is fast acting optical NUC shutters for uncooled thermal imaging devices. Another one is field-of-view changers in binoculars and other real-time image devices. Also they could be used as a drive for chock flaps, gate doors, fuel valves in internal combustion engines; in Safe & Arm modules of FUZEs, etc.

Below two implementations are elaborated.
