Abstract
A click mechanism of slide volume control ensures judgement of a center stop position of a lever by a difference in the click touches and allows many stop positions of the lever by providing holes on both sides of the lever inserting hole of the upper surface plate of the frame and providing convex portions on the ends of elastic arms of a plate spring which engage the holes.
Claims7
A click mechanism of a slide lever control, comprising:
- a frame having a surface provided with an elongated center hole, at least one stop hole on one side of said center elongated hole, and a plurality of stop holes formed in two sets on the other side of said center elongated hole;
- a plate spring having an elastic arm formed on each of two sides thereof;
- a slide lever mounted with said plate spring on a slider receptacle slidably disposed in said frame with said slide lever protruding from said center elongated hole of said frame and said elastic arms of said plate spring extending toward and engageable with the stop holes on the respective sides of said frame,
- wherein said one stop hole on said one side of said frame is located such that the elastic arm on one side of said plate spring engages said stop hole to define a center stop position between the two sets of stop positions defined by said two sets of stop holes on the other side of said frame engageable with the elastic arm on the other side of the plate spring, whereby a difference in the click touch of said center stop position from the other stop positions can be detected.

- a plate spring having an elastic arm formed on each of two sides thereof, wherein the elastic arms have convex portions formed on the ends thereof;
- a touch plate mounted to said plate spring having holes therein through which the convex portions of said elastic arms of said plate spring protrude;
- a slide lever mounted with said plate spring and said touch plate on a slider receptacle slidably disposed in said frame with said slide lever protruding from said center elongated hole of said frame, and said elastic arms of said plate spring extending through said holes of said touch plate toward and engageable with the stop holes on the respective sides of said frame in order to define respective stop positions of said slide lever.
