Here is to introduce the characteristics of 86 switch socket and 118 switch:
1, most of the 118 type switch socket is multifunctional plug, the internal current carrying copper structure is complex, in order to adapt to the insertion of different plugs and can not do the maximum internal copper and plug contact surface, even the contact surface is very small, the clamping force of the copper on the pin is not enough. For small power electrical appliances such as chargers, lamps and so on, but in the electrical types of power is big today, this kind of socket will bring electricity safety risks, easy to cause contact point heat and even burn out the situation of socket plug.
2, due to the internal copper processing and complex structure, its mechanical strength and life is generally short. Some of the middle and low grade even rough processing, copper stamping, bending and other not in place or excessive, make the jack part of copper irregular, the consequences and plug is not in place or make the plug appear too loose, too tight to insert the phenomenon, a long time will affect the life of wall switch socket and plug.
3, 118 switch is modular free combination, many dilettante consumer convenience and decoration workers, often put the heavy current and weak current module combination in a panel, such easy to cause the result of the weak current interference, and may even appear high voltage wire didn't answer tight, loose and in the case of weak current modules on the terminal, the consequences are computer and TV burn-in.
4, 118 switch this kind of multifunctional socket seems to be convenient to use, can adapt to a variety of different foot shape plug, but the other way around is not, a wall switch socket module inserted into the three-hole plug can not be inserted two holes, only inserted in the panel of another module. The Model 86's five-hole panel is equivalent to one of its modules, but the Model 86 can insert both three-hole and two-hole inserts.
