Patent

CA 2413532

A lamp comprises a light source (1), a battery (2) and a switch unit (3) which are electrically interconnected. The lamp's reliability, wear life and corrosion resistance are increased by the switch unit being a magnetic switch (3), which by means of an electrically insulating moulding material is moulded in the same unit as the light source (1) and the battery (2), and which is operated externally by a movable magnet (4).

Une lampe comprend une source de lumière (1), une pile (2) ainsi qu'une unité de commutation (3) lesquelles sont interconnectées électriquement. La fiabilité de la lampe, la durée de vie ainsi que la résistance à la corrosion sont améliorée par le fait que l'unité de commutation est un commutateur magnétique (3), lequel, à l'aide d'un matériau de moulage électro-isolant, est moulé dans la même unité que la source de lumière (1) et la pile (2), et est commandé depuis l'extérieur par un aimant mobile (4).
