CLICK MECHANISM FOR ELECTRIC PARTS

摘要

A click mechanism is provided so that an entire region of 360° rotation can be effectively used and the number of clicks can be freely set. The click mechanism comprises a spring 50 made of a plate material and disposed on a rotatable plate 40 that rotates integrally with a rotationally-manipulated shaft 10 of an electric part; two cylindrical click pieces 60 disposed on an outer perimeter of the rotatable plate 40 in positions forming an angle of 180° with respect to each other so as to retractably protrude from the positions at different heights on the outer perimeter in an axial direction of the rotationally-manipulated shaft 10; and projections and depressions 32 and 33 formed on an inner perimeter of a housing 30 for the rotatable plate 40 in a circumferential direction, in two upper and lower tiers in the axial direction. The projections and depressions 32 and 33 in the two upper and lower tiers are staggered in the circumferential direction and the two click pieces 60 are biased by the spring 50 to be in resilient contact with the projections and depressions 32 and 33 in the two upper and lower tiers at perimeters thereof.
