Material
Conductive contact parts---All the parts are over 20¦Ìm silver coating, preventing from oxidation easily.
Insulator--- Silicone Rubber insulator has the performance of light weight, waterproof and non-brittle.
Base plate---Stainless steel or hot galvanizing base ensures reliable manipulation & corrosion resistance.
Feature & Advantages
1 Stainless steel disc spring bowl¡ª 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.
