Abstract

PURPOSE: To achieve the simplification of wiring, adjustment and repair works by mutually opposing the chassis secured with electric parts to be operated from the outside and a printed sheet, face to face, and drilling holes in the chassis in the positions oppossing to the electric circuit parts.
CONSTITUTION: To couple a chassis 30 and a printed sheet 40, its engaging pieces 32, 32a are respectively inserted into engaging holes 41, 4a and posts 33, 33a are deviated in the arrow A direction, then the sheet 40 is firmly held in place between the engaging pieces and posts owing to the deviation of the chassis 30 because the engaging pieces are formed in taper form. To secure a see-saw switch 50 to the chassis, the switch 50 is moved in the arrow B direction and the switch body 51 is inserted onto a mounting tip 34, then the engaging piece 54 slides to a step part 35 and deflects inward because it has elasticity in the inward and outward directions and is formed tapered outward. When its front part 52 touches the edge of the hole 34, it disengages from the step part 35 and is secured to the chassis 30.
