Description

[Detailed description of the invention] This invention relates to a stop switch that selects and holds the ON and OFF positions. Because the device conducts electricity between both fixed terminals, there are many parts and many processes such as caulking and soldering, which inevitably leads to high costs. An object of the present invention is to provide a stop switch that provides reliable operation at low cost and has an extremely simple structure that uses body ground to ground and stop the motor.

An embodiment of the present invention will be described with reference to the accompanying drawings. Reference numeral 1 denotes a switch body made of a non-conductive material such as synthetic resin or hard rubber, in which a fixed housing 2 on the body B side and an operating lever 10 rotate. The primary voltage terminal X is movably assembled and formed on the fixed housing 2.
and body ground terminal Y can be turned ON and OFF in conjunction with the rotation of the operating lever 3. To explain its structure, the fixed housing 2 is located in an enclosed space surrounded by an annular wall 3. 4, a tapered through-bearing connection part 6 is bored in the bottom part 5 of the operating lever 1, and a three- to four-part bite fixing part 7 is integrally protruded in the lower end of the bearing in the radial direction.
0, the primary voltage terminal X is exposed at an appropriate position on the inner wall of the annular wall 3, and the body ground terminal Y is connected to the inner space of the annular wall 3 where the primary voltage terminal X is exposed. It's forcing me to play. As shown in FIGS. 4 to 6, the body ground terminal has a strip material bent in an inverted three-shape, and the upper part 15 is engaged with the notch part 19 and the notch part 20 of the annular wall 3, and the outer surface part 17 is bent. is brought into contact with the body B, and the lower part 16 is made to have an outward expansion force from the surrounding space part 4 as shown in FIG. It is normal to be in a state of bullet contact with. That is, in this state, the primary voltage terminal X and the body ground terminal Y are connected and energized, and the primary voltage of the engine is grounded to the body, and the engine is stopped.

Reference numeral 10 has an annular groove 22 in which the annular wall 3 of the fixed casing 2 fits, and a rotation shaft 1 in the center of the ceiling.
1 is a vertically disposed operation lever, and the hakama part 12
On the inner wall, there is a display flange 8 of the fixed housing 2.
The circumferential portion of the rotating shaft portion 11 is fitted into the bearing connecting portion 6 by engaging the claw portion 13 that restricts rotation of the operating lever 10 only during ON and OFF periods into the notch recess 9 of the annular wall 3. The end hook portion 18 of the body ground terminal Y is engaged with the biting portion 23 protruding from the annular wall 3.
The corresponding surface corresponds to the moderation notch 21.

Now, as shown in FIG. 6, at the lower part 16 of the body ground terminal which comes into elastic contact with the inner wall of the annular wall 3 by its own outward expansion force, the operating lever 10 of the rotary shaft part 11 that engages the terminal hook part 18 is located at the display flange. When the pointer section 24 points to OFF of 8, the primary voltage terminal
is connected to body ground terminal Y to keep the engine stopped, and from this position, operate lever 1.
0 to Figure 5 and then to Figure 4 by moving the operating lever 10.
When rotated in the ON direction, the body earth terminal Y is caught in the rotating shaft part 11 of the lever, and the half diameter of the lower part 16 of the body earth terminal Y that comes out gradually becomes smaller, and gradually from the primary voltage terminal It becomes loose and has to be held in the ON position to allow the engine to start.

Since the present invention has the above configuration, the fixed housing 2
The operating lever 10 can be integrally molded from a non-conductive material such as synthetic resin or hard rubber, making mass production possible with a small number of parts, and the operating lever 10 can be easily attached to its rotating shaft 11 during the assembly process. The two-split head of the lower end of the shaft is attached to the bearing connecting portion 6 by a simple operation of engaging the end hook portion 18 of the body earth terminal Y protruding into the annular wall 3 with the biting portion 23 and pushing it. The part 25 bites into the fixing part 7 while expanding outward, and can be fitted and connected, and in the assembly process, the outer periphery of the annular wall 3, the outer periphery of the rotating shaft part 11, and the primary voltage terminal By applying grease to the insertion part of the X, etc., the sealing performance is ensured, so this is an excellent practical idea that can also exhibit excellent waterproof functions.
