PUSH SWITCH TYPE INPUT DEVICE

摘要

PROBLEM TO BE SOLVED: To improve the operability of a push switch while increasing the total number of movably operated push switches. SOLUTION: Push switches 13-27 are dispersively arranged in a sector form. The area of the contact operating faces 131-171 of the push switches in the farthest position on the extending side (the side opposite to a point P) of the sector form is set larger than that of the contact operating faces 231-271 of the push switches 23-27 the nearest position on the converging side (the point P-side) of the sector form. The area of the contact operating faces 131-271 of the push switches 13-27 is set larger toward the extending side of the sector form. COPYRIGHT: (C)2004,JPO
