Material
Conductive contact parts---All the parts are over 20μ silver coating, preventing from oxidation easily.
Insulator--- Porcelain insulating post provides the performances with ultraviolet resistance, erosion resistance, and waterproof.
Base plate---Stainless steel or hot galvanizing base ensures reliable manipulation & corrosion resistance.
Packing
1 piece per poly bag, each product is wrapped with poly foam inside and standard carton outside.
Feature & Advantages
1 Stainless steel disc spring bowl— It makes two contact parts much more tighten, and supplies very low resistance.
2 Operation pull ring--- The lever design of pull ring and shift lock-pin ensures high breaking ability.
3 Contact methods---using surface contact instead of point contact, the device prevents too large resistance leading to heat too fast, and provides fire protection as well.
