Abstract A novel micro shock switch with very small size at micro-scales, was designed and fabricated with establishment of simple fabrication protocols, compared to existing recipes so far. The switch is composed of three main parts-the spring, fixed electrode, and movable electrode with additional mass. Main components are made of nickel, which has many benefits for shock switches. Theoretical and experimental investigations were performed to design a shock switch. A system for evaluating performance of the shock switch was set up, and performance tests were conducted, to obtain threshold impact which can be detected, using the fabricated device. The fabricated device was turned on at 670 g in the vertical direction, and had a much faster response time of 0.3 ms, than conventional devices.
