Abstract
A portable light or device may comprise: a light source or operative element; a switch for controlling energization of the light source or operative element; and a housing supporting the light or operative element and the switch. The housing has a compartment having a relatively larger transverse dimension in one region for receiving a battery having a corresponding larger transverse dimension and has a relatively smaller transverse dimension at least at one end thereof for receiving a battery having a corresponding smaller transverse dimension. At least one electrical contact in the compartment is movable for making electrical connection to batteries having a relatively shorter length and a relatively longer length.
