<p>PROBLEM TO BE SOLVED: To facilitate the design of components and the management of dimension accuracy by forming a signal armature in a columnar shape and forming the tip part of a ground armature in a ring shape surrounding the signal armature. SOLUTION: For the ground armature 16, a wound part 16b wound in a spring shape with a supporting point 19 as a center is formed and the tip part 16a of the ground armature 16 is provided with elastic force. Also, the tip part 16a of the ground armature 16 is wound about one and half turns so as to surround a contact protective piece 18 and formed in the ring shape. Also, the other ends of bar-like conductors 15a and 15b for forming a spring contact 15 on one end are respectively soldered to a signal line 9a and a ground line 9b formed on the printed board of a controller 9. Also, the other ends of the ground armature 16 and the signal armature 17 are passed through the bottom part of the magazine receiver 10c of a battery case 10 and respectively soldered to the ground line 9b and the signal line 9a. Reset is surely performed by the simple constitution of parts without requiring the dimension accuracy so much.</p> |
