A contact-breaker device that can be miniaturized, realize low power consumption and low cost, and generate an irregular pulse current by causing irregular electrical conduction and insulation of a circuit. The wiring topology includes multiple sources, multiple sinks and multiple wires. A magnetization direction of the free layer is switchable by application of the Rashba field and the external magnetic field to the free layer. While traveling up, the wings are powered by a positive lift force and drag force while using negative lift force and drag force when traveling downward.
