Abstract
A rotary pulse switch for digital tuners or the like comprises a rotor which is provided with a plurality of protrusions spaced at equal intervals on the peripheral edge of one surface thereof and to which an operation rod is fixed. A housing receives the rotor in a rotatable manner and contact members are respectively disposed at right and left ends within the housing. A member slidable rightwards and leftwards is held midway between both the contact members. By rotating the operation rod a predetermined angle clockwise or counterclockwise, the protrusion of the rotor moves the slidable member rightwards or leftwards so as to be able to turn the contact member "on" repeatedly at the right or left end.
