Rotating switchable dial

Abstract

This item consists of three plates: a front plate, a rotating plate, and a locking plate. The rotating plate is secured by a metal fitting in the center of the front plate. The locking plate is secured by a metal fitting in the upper left corner of the front plate. A round hole in the front plate displays part of the text printed on the rotating plate. The text displayed can be easily changed by rotating the rotating plate. The tip of the locking plate fits into the wedge-shaped notch in the rotating plate, guiding it to the correct position and preventing accidental rotation. The tip of the locking plate points to the number printed on the front side. To rotate the rotating plate, rotate the locking plate clockwise to unlock it, as shown in Reference Figure 1. By changing the text as shown in Reference Figures 2 and 3, it can be used for a variety of purposes.
