Switch common switch terminal screw-type terminals of the pillars, the parallel plate-screw-type terminals, the saddle screw-type terminals and fast no thread wiring terminals. Pillars screw-type terminals is the most widely used.
   
Pillars screw-type terminal is a more traditional wiring of the biggest advantages of this wiring is very convenient and can provide a good clamping force. We do the terminals are: bulky pillars, so the heat dissipation of the terminals itself to be very good. The high-current switches, sockets, high temperature rise, it is generally with studs terminals to heat to temperature rise test requirements. Screw huge pressure would lead to a slight deformation, and firmly press and hold the wire to make it difficult to emerge.
   
Screw-type terminals of copper pillars also has drawbacks, Elinker electrical screw wire crushed even pressure off, the cost is higher relative to other screw-type terminals, pillars and copper riveted Office would result in higher contact resistance, tighten the screw when the pillars may be relatively copper to produce rotation, which can cause serious consequences. However, as the common terminals of the switch, the pillars screw-type terminals or a good choice.
