The present disclosure provides a microelectromechanical systems (MEMS) igniter which is an ignition safety device (ISD) in a small, low-cost, low-power, and highly reliable design. The MEMS igniter provides both out-of-line safety and an ignition mechanism for a rocket motor. The igniter is initially held in a safe, out-of-line position with respect to a propellant. Upon receiving appropriate arm and fire commands and sensing the correct environment, MEMS mechanisms move an ignition component into alignment and the device can function.
