The toggle switch is mainly assembled from the following components through the corresponding process:
1. Iron shell (material: generally iron; treatment process: by electroplating nickel or blackening process to prevent oxidation)
2. Plastic handle (material: generally POM material, if there is fire retardant and high temperature resistance requirements, then PA nylon material processing technology is often used: injection molding)
3. Terminal (material: generally phosphor bronze; treatment process: electroplating silver)
4. Insulation bottom plate (material: electric wood board; processing technology: stamping)
5. Contact chip (material: generally phosphor bronze; treatment process: electroplating silver)
6. Round wave beads (material: generally stainless steel; treatment process: electroplated nickel)
7. Slingshot (Material: Bronze; Process: Stamping)
8. Decorative oil (Material: a kind of red oil or green oil chemical oil, applied to the contact part of the terminal and the bottom plate, plays a decorative role. Generally required non-toxic, environmentally friendly)
HC-134A is a hydrocarbon refrigerant blend. The primary ingredients are hydrocarbons, which are flammable substances such as propane and butane. HC-134a is available in 30 LB cylinders. Automotive refrigerants that leak out of A/C systems contribute very little to the overall global warming problem.
The U.S. EPA has issued regulations that call for R134a to be phased out of domestic new car production by 2021. R134a will still be allowed for certain export vehicles, but only until 2025. After that, all new vehicles will have to use HC-134A refrigerant. HC-134A is flammable, but the new refrigerant is safe for automotive passenger car use. The risk of fire is extremely remote in case of an accident or refrigerant leak into the passenger compartment.
Application: Replacement refrigerant of R134A.
