When the key top of this key part is pressed with a finger, an integrated key stem opens and closes the switch part. The key top of a standard key part is approximately square with a side of about 18 mm, but frequently used keys or keys for special purposes may be longer and thinner than the standard key, or have an area several times larger than the standard key. be. Conventionally, in such special keys, the switch part 2 is installed approximately in the center of the dedicated key part 1, as shown in FIGS. 4 and 5. I couldn't change it to 2. Further, a crank-shaped interlocking rod 4 is incorporated in order to ensure that the entire key top 3 is pressed down uniformly no matter which position of the key top 3 is pressed. In addition, 5
6 is an upper plate, 6 is a lower plate, and 7 is an interlocking rod support.
