The embodiment schematically shows how the bobbin 206 and the rubber ball 207 are connected to the micro switch unit 202.

Referring to Figure 2, the bobber switch 200 is composed of two stages of the upper end is formed with the bobber 206 and the lower end is formed rubber ball 207. The top of the upper end is closed by a cap 201. The cap 201 is provided with a groove for electrical connection between the micro switch unit 202 and the outside, and a hook groove for mechanical fixing is formed. The number of the grooves may be implemented in various numbers according to the purpose of the invention, but in the present invention, it is preferable to create one groove through which two rectangular hook grooves and signal lines can pass.

Under the cap 201 is a micro switch 202 for generating a predetermined electrical signal by the operation of the bobbin 206 and the rubber ball 207 is located. The steam switch 200 of the present invention should be implemented differently according to the purpose of water supply or drainage of water, and the structure of the micro switch unit 202 is changed according to the purpose of water supply and drainage. The detailed structure of the micro switch 202 according to the water supply and drainage will be described later with reference to FIG. 3.

The bobbin 206 is connected to be positioned about the middle of the bobbin switch 200, the rubber ball 207 is connected to be located at the bottom of the bobbin switch. The bobbin 206 is to adjust the upper limit of the water supply and drainage, the rubber ball 207 to adjust the lower limit of the water supply and drainage. The connection means 203 can also be implemented in various ways to suit the level of those skilled in the art, it is preferable to use a carbon string in the present invention.

Looking at the process of adjusting the water supply and drainage by the bobbin 206 and the rubber ball 207 as follows. First, a description will be given of a process in which the water supply is stopped when the target water level is reached in order to constantly adjust the upper water level when the water is supplied to the tank. When water is started in the tank and the water supply starts, the rubber ball 207 struck down by the force of gravity is brought up by the buoyancy force by the water as the water rises. The micro switch unit 202 then recognizes that water is being supplied. If the water continues to supply water and the water level of the tank is formed to the place where the float is located, the float 206 is no longer subjected to gravity force and is buoyant force. When the float 206, which is buoyant, is also loosened, the micro switch 202 is operated to stop further water supply. This process will be described in detail with reference to FIGS. 3A and 4 to be described later.

Hereinafter, the water drainage process will be described.

The drainage process of the water is performed in a reverse process to the water supply process. When the water in the tank is insufficient or drained, the process of water supply will be explained when the lower limit level is exceeded in order to constantly adjust the lower limit level of the water.
When the tank is filled with water, the bobber 206 and the rubber ball 207 float naturally due to the buoyancy of the water. However, if the water level is lowered in the tank later, and lower than the portion where the bobber 206 is located, the bobber 206 is no longer buoyant of water and is subjected to gravity force, so that the deflection is lowered. Pull the carbon cord 203 connected to the bobber (206). At this time, the micro switch unit 202 detects such a movement to detect that the water level of the current tank is lowered. If the water level for the water tank continues to be lowered, the rubber ball 207 is lowered to where it is located, since the rubber ball 207 is lower than where the rubber ball 207 is also no longer buoyant because of the water You will receive the force of gravity. The force of gravity causes the rubber ball 207 to be struck down and the micro switch unit 202 detects this to start water supply. This process will be described in detail with reference to FIGS. 3B and 4 to be described later.
