Problems solved by technology
[0005] Through the above-mentioned technical solution, that is, by setting the thyristor to quickly cut off the power supply in case of overvoltage, overcurrent, etc., the sensitivity is greatly improved, and the protection can be realized more quickly. However, in the protection process, it is still impossible to protect some Small electrical appliances are used for protection, and the rated current of general protective switches is greater than 10A. The overcurrent of small household electrical appliances generally does not exceed the rated current of the protective switch, so it will not trip, so it is often possible to burn out household appliances and cause fires. If the phenomenon occurs, using the protective switch on the market to protect can only protect the situation of large overcurrent, not to mention the protection of small household appliances with a rated current below 1A

Embodiment Construction
[0044] refer to Figure 1 to Figure 11 Shown, the embodiment is described further.
[0045] A protective switch for household appliances disclosed by the present invention comprises a seesaw 2, a linkage plate 3, a fixed bracket 4, a first connecting pin 5 and a second connecting pin 6, and the first connecting pin 5 is provided with a first static contact 51, the second terminal pin 6 is provided with a second static contact 61, the first terminal pin 5 and the second terminal pin 6 are respectively connected to different electrical appliances, so that one protection switch can control the opening and closing of two electrical appliances.
[0046] The seesaw 2 is interlocked with the linkage plate 3 and drives the linkage plate 3 to move longitudinally. The seesaw 2 is provided with a mounting shaft, and the linkage plate 3 is provided with a mounting hole for the installation shaft to pass through. By pressing the seesaw 2. Make the installation shaft drive the linkage plat...

The invention discloses a protective switch for household appliances, which solves the problem that the protective switches on the market cannot protect small household appliances with a small rated current. Adjusting the size of the output voltage, the household appliance protection switch of the present invention, through the setting of the adjustment unit, can allow the operator to adjust (load) the overcurrent limit required by the electrical appliance at will, so as to adapt to various power household appliances and improve the convenience of use , realize the protection of household appliances with different power levels, and then protect small household appliances with smaller currents, avoid damage to small household appliances when overloaded, and then protect the entire protection switch from being damaged; at the same time, there is short circuit protection, And can play a role in fire prevention, but also can ensure the integrity of the entire protection switch.
Description
technical field [0001] The present invention relates to a protection device, more specifically, it relates to a protection switch for household appliances. Background technique [0002] With the development of science and technology, household appliance protectors are gradually needed by people. The household appliance protector is a multifunctional protector with overload protection, short circuit protection, overvoltage protection, overheat protection, etc., such as circuit breakers, etc., can To provide reliable protection for the protection of electrical appliances and property safety. [0003] However, the various protectors currently used do not have the function of quickly protecting electrical appliances. When household appliances are overloaded for some reason, they are prone to heat and fire. Since ordinary switches do not have the function of automatically disconnecting the power supply, fires will still occur after the switch is burned. , while 10A-20A small cir...
