Abstract
PURPOSE:To achieve the reduction in the number of parts and the improvement in reliability by making the wiring patterns formed on the inside wall of the through-hole of a printed substrate and one end of a switch return spring contactable and detachable. CONSTITUTION:Through-hole plating and gold plating are applied to the inside wall of the through-hole 1a of a printed substrate 1 which is placed with a battery 9, etc. and is secured with a circuit support base 3 and a device cover 10 by means of screws 11, 12, etc. to form a kind of contact electrodes by wiring patterns 1b. The contact piece part 8b of an approximately C-form switch return spring 8 whose one end 8a is contacted to the electrode of the battery 9 is inserted into the through- hole 1a. Then, when a switch button 15 is pushed, the contact piece part 8b makes contact to the wiring pattern 1b and becomes switched ON. When the switch button 15 is released, said part is reset by spring action and becomes switched OFF.
