Abstract (en)

[origin: EP2261942A2] The switch has a liberation element (7) mounted between an actuating rod (5) and an attachment point (8) fixed relative to a fixed contact (2) to block the rod in translation. A pyrotechnic isolator (12) is provided with a cutting tool for cutting the liberation element. The tool is moved in translation from a retracted state to a triggering state when the isolator is ignited, the rod is released and displaced, an elastic element (9) is triggered, and the switch is closed. An independent claim is also included for an electric circuit comprising electronic components associated to a switch.
