摘要： According to the present invention there is provided a catch device (21) for use in controlling the movement of a closure, the device comprising: first and second magnetic elements (5, 6) spaced apart from each other; and a movable element (9) such as a keeper element, preferably arranged relative to the magnetic elements, the movable element being movable between first and second holding positions wherein in the first holding position the movable element (9) is held by a magnetic force of the first magnetic element (5) and in the second holding position the movable element (9) is held by a magnetic force of the second magnetic element (6); and means (12) for releasing the movable element from one of the holding positions, the released movable element moving to the other holding position, the device being such that the movement of the closure can be controlled in dependence on the position of the movable element.
