となる。Next, the spring load characteristics R1 to R3 in the sections of the strokes S1 to S3 will be described with reference to a graph. The spring load characteristic R1 in the section of the stroke S1 is the contact spring 1
5 is a load characteristic, which is a straight line with a gentle slope. The spring load characteristic R2 in the stroke S2 section is determined by the contact spring 1
5 is obtained by adding the load characteristics of the elastic body 19 to the load characteristics of No. 5, and the inclination is slightly increased. The spring load characteristic R3 in the section of the stroke S3 is obtained by adding the resistance of the contact terminal plate 16 to the sum of the load characteristic of the contact spring 15 and the load characteristic of the elastic body 19, and is a straight line having a steep inclination. When there is no elastic body 19, the load characteristic is as shown by a broken line.
