ABSTRACT:
A pressure-responsive mechanical switch for use in conjunction with integ rocket-ramjet engines. The switch may only be activated when two pressure sources acting thereon meet certain preselected conditions and includes a pair of selectively interlocking pistons mounted within a pair of bores disposed in a housing. The pistons are independently acted upon by the forces produced by pressure sources to effect activation of the switch.
