[0002] In today's society, there are all kinds of equipment and devices driven by electricity. In order to effectively manage whether the power is transmitted or not, various types of switches are usually required to be set up to control whether the power is transmitted to the equipment and devices by using the switches; and on yachts, ships and other equipment and devices that are respectively equipped with multiple batteries as power sources, since it is necessary to turn on or off two groups of different and separated electrical equipment at the same time, so that each of the two electrical equipment is powered by a different battery, or two independent circuits are connected together, so that both groups of electrical equipment will be powered by two different batteries connected in parallel, so that it is provided with a rotary switch for switching between various power supply methods.

[0003] Among them, for this type of rotary switching switch, please refer to the U.S. invention patent with the announcement number US7442887B2 and the invention name “Enhanced rotary multi-pole electrical switch” which was announced on October 28, 2008. The switch is mainly provided with a first terminal, a second terminal, a third terminal and a fourth terminal, and can drive the first connecting rod and the second connecting rod to rotate when the knob is turned; when the first contact point, the second contact point and the third contact point of the first connecting rod are all in contact with the second bus bar of the second terminal, and the first contact point, the second contact point and the third contact point of the second connecting rod are all in contact with the third bus bar of the third terminal, the whole is in an open circuit state; and when the first contact point of the first connecting rod is in contact with the second bus bar of the second terminal, the second contact point and the third contact point of the first connecting rod are in contact with the first bus bar of the first terminal, the first terminal and the second terminal are in an open circuit state, and the first contact point of the second connecting rod is in contact with the third bus bar of the third terminal, and the second contact point and the third contact point of the second connecting rod are in contact with the fourth terminal. The fourth bus bar contacts, so that the third terminal and the fourth terminal are connected; when the first contact point of the first connecting rod contacts the second bus bar of the second terminal, the second contact point contacts the third bus bar of the third terminal, the third contact point contacts the first bus bar of the first terminal, and the first contact point of the second connecting rod contacts the third bus bar of the third terminal, the second contact point contacts the second bus bar of the second terminal, and the third contact point contacts the fourth bus bar of the fourth terminal, the whole is connected and conducted; and it is possible to simultaneously turn on or off two different and separated groups of electrical equipment, so that each of the two electrical equipment is powered by a different battery, or connect two independent circuits together, so that both groups of electrical equipment will be powered by two different batteries connected in parallel, thereby realizing switching of various power supply states.

[0004] However, although the above-mentioned invention patent "Enhanced rotary multi-pole electrical switch" can achieve the expected effect of switching different power supply states, it is also found in its actual operation and use that in order to smoothly contact and conduct with the first connecting rod and the second connecting rod, the second terminal and the fourth terminal of the structure are provided with extension sections extending from the inner ends of the second terminal and the fourth terminal, and the extension ends are all slender, resulting in a significant reduction in the cross-sectional area of ​​the second terminal and the fourth terminal at the extension section, which leads to the problem of increased thermal resistance during power transmission. During use, the local temperature of the extension section will be too high, which will easily cause deformation under long-term use, affecting the safety of use, and easily affecting the power transmission efficiency, and even affecting its overall service life. Therefore, there is still room for improvement in its overall structural design. Utility Model Content
