ABSTRACT:
An axially-movable rotary switch includes a casing, a fixing base, a substrate and a knob. The fixing base is fixed in the hollow casing. The substrate is fixed below the fixing base. The knob is pivotally disposed on the upper end of the hollow casing. The switching rod of the knob eccentrically penetrates a positioning hole of the fixing base. The elastic piece is disposed at the distal end of the switching rod and is brought into contact with the electrical contacts of the substrate. With the elastic piece of the switching rod being arranged to correspond to the electrical contacts of the substrate, a user can switch the states between a closed circuit and an open circuit by axially drawing/pressing the knob. Further, the contact between the elastic piece and the electrical contacts will not generate unnecessary frictional interference, so that the lifetime of the device can be extended.
