<p>The electric lock for a door has a housing (1) with two electrically separated coils (3,4) arranged in succession. The coils define an inner space for a bolt (5) which has a magnet (6) mounted on it or is partially magnetic itself. The bolt is moved by activation of the coils to a required position. The coils are operated by electronically controlled electric current impulses.</p> |
