A paper-lined dry cell battery includes an electrically insulating band over the full circumference of the inner surface of the can sidewall from a point below the level of the upper end of the liner to a point substantially thereabove, thereby to electrically insulate a segment of the can sidewall from smears.

The switch includes a slide, mounted for movement along the housing between first, second and third positions, and carrying a depressable pushbutton. A flexible contact is movable by the pushbutton to a position wherein it is operatively connected to a fixed contact to complete the electrical circuit. The pushbutton and the flexible contact each have corresponding camming and non-camming surfaces thereon which respectively interact to move the flexible contact towards the fixed contact. The corresponding camming surfaces interact only as the slide is moved from the second to the third position. The corresponding non-camming surfaces interact only when aligned and the pushbutton is depressed. Since none of the surfaces operatively interact as the slide is moved from the first toward the second position, wearing of the interacting surfaces is substantially reduced.
