Kitchen cooker extractor hood switch

Used to fix broken cooker extractor hood light switch. The device clips in to the bottom of extractor hood and needs to be fixed at the top. I use a strong magnet; you may prefer to drill a small hole and use a self tapping screw.
It is not possible to take the whole switch assembly apart without damage/destroying it; this fix enables the continued use of the kitchen cooker extractor hood which would otherwise need replacing.
