ABSTRACT:
A rotary variable resistor with switch having a switch mechanism, in particular, a rotary variable resistor with switch corresponding to an ultrathin rotary variable resistor. Such a rotary variable resistor having a switch mechanism has dimensions, especially thickness, which are only slightly larger than that of a conventional ultrathin rotary variable resistor. Moreover, such a rotary variable resistor is easy to assembly due to the small number of parts, is reliable, and generates a fairly loud and easily recognizable clicking sound each time the switch is turned on or off, which can be both easily felt and heard by the user.
