PUSH BUTTON SWITCH STRUCTURE FOR ELECTRIC APPARATUS DEVICE

摘要

PURPOSE:To improve the assembly workability by confirming whether a push button switch section is completely constituted or not when the push button switch section is assembled before the whole is assembled. CONSTITUTION:A push button switch fitting section 25 fitting a push button switch section is provided on an upper case 1, and a coupling hole section 9c is provided on a logic package 9 having multiple keys 11 at the front edge section. Push button units 4 are arranged on the right and left of the front section of a case main body 4A, and push buttons 4a are fitted to the case main body 4A via springy push button connecting pieces 4c. A coupling section 28 is formed on the case main body 4A, and the coupling section 28 is coupled with the coupling hole section 9c of the logic package 9 to fit the front edge section of the logic package 9 to the push button units 4. Tips 11a of the keys 11 are brought into contact with back faces of the push buttons 4a to constitute a push button switch section, and the push button switch section is fitted to the push button switch fitting section 25 of the upper case 1 when the logic package 9 is thrust.
