The toggle switches are categorized into low-current and high-current toggle switches, featuring intelligent functions such as delay, expansion, external synchronization, anti-interference, high reliability, stable operating area, and self-diagnosis. Components of the toggle switches include slingshot, terminals, insulating base plates, contact code pieces, and circular beads. Now, what materials are the components of the toggle switches assembled from?

1. Crossbow (Material: Bronze; Processing Technology: Pressing Molding)

Terminal (Material: typically phosphor bronze; Treatment Process: silver plating)

3. Insulating Base Plate (Material: Epoxy Laminated Board; Processing: Stamp Forming)

4. Contact Chip (Material: typically phosphor bronze; Processing: electroplated silver)

5. Round Pearl Beads (Material: typically made of stainless steel; finishing process: electroplated nickel)

6. Iron Shell (Material: Typically made of iron; Processing: Electroplated with nickel or black oxide treatment to prevent oxidation)

7. Plastic Handles (Material: Generally made of POM; for fire-retardant, flame-retardant, and high-temperature requirements, PA nylon material is often used; Processing Technology: Injection Molding)

8. Decorative Oil (Material: Red Oil or Green Oil, a type of chemical oil, used to coat the contact area between terminals and the baseboard for decorative purposes. Generally required to be non-toxic and environmentally friendly.)
