Abstract
A digital switch may have an advantageous actuating member including, in addition to pawls for a ratchet mechanism, a pair of main bodies and spring portions integrally formed therewith, whereby the mechanical integrity of the actuating member and smooth operation are assured. The spring portions are interconnected by a mounting plate which is in turn engaged to a casing member. The switch may include an advantageous electro-conductive pattern which is made by insert molding an embossed metallic plate into synthetic resin, whereby the dimensional accuracy of the pattern is assured and the production may be facilitated. Further, the switching element may make use of a set of concentric cams which selectively drive movable contact pieces onto fixed contact pieces according to the step-wise rotation of a ratchet wheel.
