Abstract: A torch is disclosed which comprises a casing for receiving a cell and a head which screws onto the casing. The head contains a light bulb, a mounting for the bulb and a reflector. The cell is gripped while it is in the casing to prevent it moving freely along the casing. It can, however, move when the torch is tapped on one or other end or is knocked on a surface with sufficient force to overcome the restraint which is applied to the cell. The cell can also be caused to move by `flicking` the torch. The cell can be gripped by a leaf spring which extends along the casing between the cell and the inner face of the casing, the leaf spring being slightly deformed as the cell is pushed into the casing and thus exerting a lateral thrust on the cell. Alternatively, there can be a wedge which when pushed into the casing urges the cell laterally. In another form the casing itself can be closed onto the cell when the head of the torch is screwed onto the casing.
