PURPOSE:To enable each of primary battery and secondary battery having a same diameter and individual different lengths to use in a same battery case by providing a first contact holder equipped with a resist sliding contact member and a selector switch controlled thereby. CONSTITUTION:When first battery 6 is mounted, the first battery 6 is held by a battery holder 1, a first contact member 3 and a second contact member 5 to supply electric power from each terminal 3a, 5a. Hereon, a selector switch 8 is in OFF position because an actuator 8a of the selector switch 8 is not contact with a first contact holder 2. When second battery is mounted, the first contact holder 2 slides with an energization member 4 toward the opposite direction of an arrow indicating energization direction and the second battery 7 is held by the battery holder 1, the first contact member 3 and a second contact member 5 to supply electric power from each terminal 3a, 5a. Hereon, the selector switch 8 is in ON position because the actuator 8a of the selector switch 8 in contact with the first contact holder 2. |
