Abstract
A click knob assembly that has a fixture having a circular inner surface defining uniformly spaced ridges separated by grooves and a knob, set in the fixture, and including a user accessible portion; a spring holder, attached to the user accessible portion; a spring assembly, engaged to the spring holder; and a first plunger and a second plunger engaged to the spring holder, each facing the circular inner surface, in opposed direction to each other, and each being pushed outwardly by the spring assembly, and thereby being pressed into the circular inner surface. The first plunger includes a click surface sized and positioned to engage the uniformly spaced grooves. When the knob is rotated, the click surface is pushed over a ridge, and then falls into a groove, making a click sound and both the plungers are maintained in contact to the circular inner surface by the spring assembly.
