The toggle switch is mainly assembled by the following components after the corresponding process treatment:
1. Iron shell (material: generally iron; Treatment process: by electroplating nickel or black process to prevent its oxidation)
2. Plastic handle (material: generally POM material, if there are fireproof flame retardant and high temperature resistance requirements, PA nylon material is often used Treatment process: injection molding)
3. Terminal (material: generally phosphor copper; Treatment process: electroplated silver)
4. Insulating bottom plate (material: bakelite board; Treatment process: stamping)
5. Contact code sheet (material: generally phosphor copper; Treatment process: electroplated silver)
6. Round beads (Material: generally stainless steel; Treatment process: electroplating nickel)
7. Slingshot (Material: Bronze; Treatment process: stamping)
8. Decorative oil (material: red oil or green oil A kind of chemical oil, applied to the contact part between the terminal and the bottom plate, play a decorative role. General requirements are non-toxic and environmentally friendly)
