With the development of society, various electrical appliances are continuously developed and utilized, and the electrical appliances need electric energy for working. Thus, the use of power switches is very widespread, and various types of power switches such as mechanical, electromagnetic, and semiconductor are available on the market. The mechanical power switch has the lowest cost, so that the mechanical power switch can be applied to the most alternating current power supplies, particularly 100-400V alternating current power supplies.
A feature of mechanical power switches is that the two electrodes that need to be switched on are physically touching and separated. In most cases, the electrode shape is irregular, such as a knife switch and a leaf switch. Such electrodes cause non-uniform electric field distribution near the contact point and excessive local electric field intensity. Often causing an ionizing breakdown of the surrounding air medium, forming a spark. Thereby presenting two serious concerns. One is that sparks can cause fire accidents and even detonate surrounding flammable and explosive substances. Another is that the ionization spark causes local excessive temperatures to sinter the contact points, while the sintered parts increase the electrical resistance causing the contact points to overheat, creating a fire hazard.

The length of the body of the connecting rod 101 is in the left-right direction, and the cross section of the body of the connecting rod 101 in the left-right direction is trapezoidal. The length of the two ends of the connecting rod 101 is in the left-right direction, and the cross section of the two ends of the connecting rod 101 in the left-right direction is rectangular. The body of the connecting rod 101 is located between the first electrode pad 105 and the second electrode pad 102, the lower surface of the first electrode pad 105 is an inclined surface inclined upward to the left and downward to the right, and the upper surface of the second electrode pad 102 is an inclined surface inclined downward to the left and upward to the right. The upper surface of the body of the tie bar 101 is a slope inclined upward to the right and downward, and is disposed opposite to the lower surface of the first electrode pad 105.

Fig. 2 is a modification of fig. 1, in which only the lower surface of the body of the tie bar 101 and the upper surface of the second electrode pad 102 in fig. 1 are changed from a slope to a flat surface, and the principle of the operation method is the same as that of fig. 1.
Fig. 3 is another modification of fig. 1, in which only the upper surface of the body of the tie bar 101 and the lower surface of the first electrode pad 105 in fig. 1 are changed from a slope to a flat surface, and the operation method is the same as that of fig. 1.
Fig. 4 shows a fourth power switch structure, which mainly comprises a connecting rod 101, a second electrode base 102, a second electrode 103, a first electrode 104, a first electrode base 105, a second iron block 201, a second magnet 202, a spring 203, a first iron block 204, and a first magnet 205.

A spring 203 is fixedly mounted on the left side of the body of the connecting rod 101.
The method of operation of the present invention is described in detail below with reference to FIG. 4:
in an initial state, the first iron block 204 is attracted to the first magnet 205, a gap exists between the connecting rod 101 and the first electrode base 105 and between the connecting rod and the second electrode base 102, the spring 203 is not deformed, the first electrode base 105 is disconnected from the second electrode base 102, and the first electrode 104 is disconnected from the second electrode 103;
the spring 203 is pushed to the right, the spring 203 is gradually compressed, at the moment, the connecting rod 101 does not displace, the spring 203 is continuously compressed, when the elastic force of the spring 203 is greater than the attraction force of the first magnet 205 to the first iron block 204, the connecting rod 101 is separated from the first magnet 205 instantly, the second iron block 201 is adsorbed on the second magnet 202, so that the upper surface of the middle part of the connecting rod 101 is in close contact with the lower surface of the first electrode base 105, the lower surface of the middle part of the connecting rod 101 is in close contact with the upper surface of the second electrode base 102, the connecting rod 101 is communicated with the first electrode base 105 and the second electrode base 102, the first electrode 104 is communicated with the second electrode 103, and the power switch is;
the spring 203 is pulled in the left direction, and the spring 203 is gradually extended without displacement of the link lever 101. When the spring 203 is pulled continuously, and the elastic force of the spring 203 is larger than the attraction force of the second magnet 202 to the second iron block 201, the connecting rod 101 is separated from the second magnet 202 instantly, and the first iron block 204 is adsorbed on the first magnet 205. At this time, the upper surface of the middle portion of the connection bar 101 and the lower surface of the first electrode base 105 are separated from each other, the lower surface of the middle portion of the connection bar 101 and the upper surface of the second electrode base 102 are separated from each other, the connection bar 101 and the first electrode base 105 and the second electrode base 102 are separated from each other, the first electrode 104 and the second electrode 103 are disconnected, and the power switch is turned off.
There are two other variations of the mid-power switch configuration of fig. 4. One is to interchange the positions of the first iron block and the first magnet, and to interchange the positions of the second iron block and the second magnet at the same time; the other is to change the first iron block into a magnet (third magnet) and the second iron block into a magnet (fourth magnet), and to control the polarity of the magnets to connect and disconnect the connecting rod 101 with the first electrode base 105 and the second electrode base 102. The method of operation of both variant configurations is similar to the first configuration of figure 4.
The same applies to fig. 2 and 3 for the modification of fig. 1.
Fig. 5 shows a fifth power switch structure, which mainly comprises a connecting rod 101, a second electrode base 102, a second electrode 103, a first electrode 104, and a first electrode base 105.

The right end of the connecting rod 101 in this power switch structure also serves as a conductor, and can be conducted with the second electrode 103. The contact end faces of the two are smooth, the area of the contact end faces can be made as large as possible according to actual conditions, and meanwhile the right end of the connecting rod 101 and the first electrode 104 can be sealed by insulating materials, so that the spark phenomenon when the power supply is switched on is eliminated.
The operation method of the power switch shown in fig. 5 is substantially the same as that of fig. 1, and when the first electrode base 105 and the second electrode base 102 are in the on state, the first electrode 104 and the second electrode 103 are simultaneously conducted; when the first electrode pad 105 and the second electrode pad 102 are in the off state, the first electrode 104 and the second electrode 103 are simultaneously off.

Fig. 6 is a modification of fig. 1, in which the first electrodes 104 and the second electrodes 103 in fig. 1 are formed as two electrode connecting units, and each electrode connecting unit is formed by one first electrode 104 and a corresponding second electrode 103. The two electrode connection units are separated by an insulation strip (including a first electrode base insulation strip 303, a first electrode base insulation strip 301 and a connecting rod insulation strip 302) to prevent the two electrode connection units from being short-circuited. The three insulating strips are positioned on the same straight line (vertical direction in fig. 4) and correspond to each other in position. The number of the electrode connection units can be adjusted according to actual conditions, for example, a single-pole switch only needs one electrode connection unit, a two-phase switch needs two electrode connection units, and a three-phase switch needs three electrode connection units. Any two electrode connecting units in the power switch are insulated.
