Have some common sense of toggle switches
When choosing a switch, in addition to considering the shape, but also consider the parameters, especially to pay attention to voltage, rated current and contact resistance.
The easiest way to check the band switch is to use the minimum ohm file of a digital multimeter to measure the contact resistance between the pole and the bit at the connected position. When detecting, the switch should be rotated or toggle several times, and the insulation resistance value between several knives and bits should be detected.
The invention is widely used in various fields such as instruments, instruments, electric toys, fax machines, audio equipment, medical devices, beauty instruments, etc. Input dial switch supply. Microprocessors are mainly used in military fields such as electronic equipment, mines, power systems, home appliances, aerospace, ships, missiles, tanks, etc.
In such a rapidly changing shopping center, especially in areas closely related to people's lives, laws, regulations and industry norms are very important because they can ensure that these products can work correctly according to people's requirements.
