IN THE MULTI-WAY INPUT DEVICE, AN OPERATING SHAFT (4) IS FORMED WITH A CYLINDRICAL PORTION (4C) WHICH RECEIVES A RETURN SPRING (7) THEREIN, AND PIVOT SHAFT PORTIONS (4F) OF A CONVEX SHAPE ARE FORMED ON PART OF AN OUTER WALL OF THE CYLINDRICAL PORTION (4C), THE PIVOT SHAFTS PORTIONS (4F) BEING ENGAGED BY SNAP-FINING WITH ENGAGING PORTIONS (5D) OF A CONCAVE SHAPE FORMED IN SIDE WALLS OF A SECOND INTERLOCKING MEMBER (5) WHICH DEFINE A SLOT. THIS CONSTRUCTION AFFORDS A HIGH ASSEMBLING WORK EFFICIENCY AND DISPENSES WITH A ROUND PIN OR THE LIKE SO FAR USED AS PIVOT SHAFT PORTIONS (4F).BESIDES, SINCE THE RETURN SPRING (7) IS RECEIVED IN A RECEPTACLE SPACE (4D) FORMED WITHIN THE CYLINDRICAL PORTION (4C), IT BECOMES POSSIBLE TO REDUCE THE THICKNESS OF THE MULTI-WAY INPUT DEVICE.(FIG. I)
