ABSTRACT:
The invention concerns a light within whose handle-forming plastic housing (2) a button-cell battery (3) provided with a circumferential and a center surface pole can be brought into the switch-contact position against the force of a compression spring (6), a portion of the center surface pole (MP) of the button-cell battery coming into contact with a portion of a ring-shaped contact blade (9), the compression spring being arranged concentrically to the ring-shaped section (9') which rests on the housing bottom and the circumferential pole (UP) of the button-cell battery being in continuous contact (permanent contact) with a contact spring (16) which extends substantially tangentially to the button-cell battery, and it proposes, in order to obtain a shape which is simple to manufacture, compact and reliable in use, that the compression spring (6) lie free of contact in the opening (10) of the circular ring-shaped section (9') lying on the housing bottom (7) and, in the switch-contact position of the center surface pole (MP) of the button-cell battery (3) comes onto the ring-shaped section (9' ). This shape of light can be developed so compactly that it can be used as actuating handle for a key.
