    • PURPOSE:To increase safety by protrudently installing the operating lever of a switch in a power source circuit in the wearing part on a body. CONSTITUTION:A battery pack is put in the opening 32 of a battery accommodation case 3 and a fixture 5 is turned to fix the battery pack to the case 3. A hanger 33 comprising a reverse U-sahped locking piece made of elastomer is formed on the side of an upper case 31a. A pair of connecting terminals 7a, 7b which are connected to the terminals of the battery pack are installed inside the opening 32. The terminal 7a is connected to a power source cord through a safety switch 8 and the terminal 7b is also directly connected to the power source cord. The operating lever 81 of the switch 8 is passed through a passing through groove 3a on the side of the case 3 and protruded to the inside of the hanger 33 (in a wearing part on a body). When a belt B is inserted inside the hanger 33 to wear the case 3, the operating lever 81 is pressed by the belt B and deformed to turn on the switch 8. Unless the case 8 is worn, the power source stays off to keep safety.
