A socket into which one or more circuit wiring can be inserted, through which various wiring can be inserted to facilitate connection with other circuits. NEMA wiring device must be as small as possible in order to realize frequent commutation, but also to realize braking during commutation and acceleration after commutation. Therefore, it is necessary to adopt commutation device quickly and braking device effectively. A switch is arranged between the weatherproof socket resistor and the electromagnetic switch, the fuse and the electromagnetic switch are connected with a power line, the power line is provided with a normally open switch of the electromagnetic switch, and the normally open switch of the electromagnetic switch is connected with the jack.Power sockets are generally made of some insulating materials, which makes the insulation and waterproof ability of the power sockets very strong. The power sockets are made of solid cores, and the connections of the power sockets are all made with good manufacturing technology and sealing ability. The power sockets can still have very good sealing ability after thermal expansion and cold contraction. What's more, the general service life of the power sockets is very long. If the power sockets are used at home, As long as the protection level of the power socket is IP65, of course, there are some other application environments where the protection level of the power socket can already achieve IP68. So far, the protection level IP68 is a very good protection level.At present, whether in daily life or in enterprise production, etc., they all need to use electric energy. They all have to use intelligent production equipment. Generally speaking, there are more automation devices now, mainly because the use of intelligent devices in the production process can greatly improve the efficiency, but the production devices are also electrical devices. In order to avoid some accidents, it is necessary to take safety measures. All kinds of power consumption problems are generally due to the gradual aging of the lines, and aging or short circuit is easy to happen in humid environment. Therefore, in order to use electricity more safely, one of the things that must be done when checking the circuits must be done well, and it is equally important to ensure waterproof work. All kinds of electrical equipment must use plugs, so the plug products can be replaced with power outlets.
