Linear actuator

Low profile and a linear actuator 10 having a long stroke is provided. The actuator includes a combined integral housing (14) to the telescopic piston (12). The piston may be extended by a fluid such as inflation gas provided by the piston and in fluid communication with the gas-generator. The piston is rapidly expanded across the one-shot stroke. The piston is extended to switch the energy to the fluid in the linear motion to perform work. The linear actuator may be formed through a stamping process, including the deep draw stamped from a base material of a single type. Or other metal forming processes may be used to form a linear actuator.
