Steel frame switch, the fourth-generation switch, has switch baseplate adopting 1.2mm cold-rollsteelsheets as support, surface using import pc polycarbonate material, contact being 16A rare earth silver alloy contact. The most important is that combining module and steel frame switch stably so as to switch on and off smoothly. As for the craft innovation in type, steel frame switch is international standard structure. It has the following features: changing switch baseplate from tradional plastic baseplate to special cold-rollsteelsheets, increasing the whole firmness and durability of switch. In this seemingly simple material change, in order to make plastic and steel frame these two different material combine stably, and to make switch on and off smoothly, the changing process invovles complex abrasive tool craft and match material. 

Compared with traditional switch, steel frame switch strengthen completely in the aspect of shock resistance, anti-deformation, anti-aging and antiflaming. These advantages not only give household switch product more perfect safety assurance, but also provide new choice to rigorous industrial electrical environment.
The exploded view of steel frame switch product
