<p>The system has an electromagnet with a mobile armor, a terminal lead fixed to the armor, and a shaft for transferring movement of armor to a bi-stable door. Two triangular plates create walls joined to an axis over a pivot to which terminal lead is inserted. The current produced by the movement of armor is transmitted to the door to open the door in one direction. If no current is received, the door is opened in the other way.</p> |
