ABSTRACT:
A torch has a tray (1) to receive batteries (14) and a U-shaped cover (2) which snaps into engagement embracing the tray and confining the batteries. A bulb (3) is located by a resilient formation (21) of the tray and projects partially through an aperture (38) in the web of the cover, by which it is retained. A resilient side (9) of the tray is deformable inwardly to close a contact (17) to switch on. The cover is of translucent plastics material, such as acrylic, and an underlay sheet (41) of pictorial or graphic character will be illuminated by light from the bulb diffusing through the cover.
