1396399 Housing for cell SUWA SEIKOSHA KK 7 July 1972 [22 July 1971] 31747/72 Heading H1B Battery-powered apparatus, e.g. an electric wristwatch, comprises a battery compartment 2, of insulating material, which is closed by a lid 3a. Positive terminals 3 contact the positive electrode 1c of a battery 1 when the latter is correctly positioned in the compartment 2, projecting negative electrode 1a of the battery protruding through an aperture 2a in the compartment to contact negative terminal 4 outside the compartment. If the battery is inserted the wrong way round in the compartment, no part of the battery contacts terminal 4, so preventing short-circuiting of the battery and damage to the apparatus. |
