Description

[Detailed description of the invention] The present invention relates to a single-tap time switch.

Conventionally, this type of time switch has a +1 Q setting mechanism that allows the limit stage to be set by external operation, and a -1 time setting mechanism in which a recess is formed in a part of the outer circumference of a perfect circle. Set a time limit! A rotating cam that rotates by an angle 1α (7I<) corresponding to the position, and a coaxial shaft 1 of this rotating cam are

1. The rotating cam rotates at a very low speed, and the time switch is made smaller. Since a small-diameter [111 rotary cam (1.1. It was not possible to do so, and in order for the contact point to gradually return to its original position, it was decided that the 4-slip arc should be fired with J-Q, and the direction of contact J should be shortened. At the first position of the time setting mechanism, the four parts of the rotating cam and the convex part of the switch lever are aligned, and adjusting the contact state requires operation, which is time-consuming and requires a large number of parts. There are many problems such as increased crop production and higher crop yields.

A linear guide t*1e (4 shown in FIG. 2) is formed, which makes it possible for the slider 10 to slide smoothly within the slide case 1d.

The quick-moving plate 11 has a projection 10 (I) on the lower surface of the sliter 10 shown in FIG. There is a rectangular plate mounted between the slider 10 and the slide case 1d, and the plate is mounted between the slider 10 and the slide case 1d.
