Abstract
A snap-engaging apparatus for use in a rotatable electrical component, particularly a rotatable switch or a rotatable resistor, makes it easier to find operational positions. The snap-engaging apparatus includes a rotor (3) which is formed as a hollow body to have an axial opening and a radial, or circumferential, wall (7). A leaf spring (8) is tensioned to have a U-shape with its ends (9, 11) being self supported against diametrically positioned parts of the circumferential wall (7). A snap-engaging contour wall surface (19) coaxially surrounds the rotor, with a snap-engaging nose (15), formed on an extension (14) of one end of the leaf spring, being springingly urged thereagainst in a radial direction. The circumferential wall (7) has an opening (17) through which the snap-engaging nose (15) extends.
