There are strict requirements on the specifications of the switching switch. Before you choose, you should know the specifications of the switching switch, so as to make the switching switch more suitable for our use. The following is a detailed introduction.
Dial switch, also known as sliding switch, can be widely used in computer mouse, automobile mouse, automobile electronic products, communication equipment, military products, testing instruments, gas water heater, gas stove, small household appliances, microwave oven, rice cooker, floating ball equipment, medical equipment, building automation, electric power. Toggle switches in tools, general electrical and radio equipment and other fields have been widely used in the above fields. Although small, they play an irreplaceable role.
The classification of the switchgear products: vertical, horizontal, plug-in, patch, two, three and four.
Electrical performance of the switch in various aspects:
Rated power: DC50V0.3ADC6V0.5A
