Embodiment Construction
[0031] More specifically, considering figure 1 , 2 And 3A, 3B show a pyrotechnic actuated electrical switch 11 constituting a circuit breaker, which has a housing 13 and a pyrotechnic actuated gas generator 15 installed in the housing, the housing defining a cavity 17, The structure of the cavity 17 changes when the gas generator emits gas. In this example, as further described, when the gas generator 15 emits gas under pressure, the volume of the cavity increases. A rectangular conductive blade 19 made of copper, for example, passes through the housing 13. The ends 20a, 20b of the conductive blades extend outward from the housing and thus achieve the electrical connection of the switch in a contactable manner, that is, allow the switch to be inserted into the circuit to make it safe.
[0032] According to an important feature of the present invention, before the aforementioned pyrotechnic trip (ie, before the ignition of the gas generator and the emission of gas under pressure,...
