The switch is primarily assembled from the following components, which have been processed and assembled using specific techniques:

1. Iron Shell (Material: Generally made of iron; Treatment Process: Electroplated with nickel or black anodized to prevent oxidation)

2. Plastic Handles (Material: Typically made of POM; for fire-retardant, flame-resistant, and high-temperature requirements, PA nylon is often chosen; Processing Technology: Injection Molding)

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

4. Insulating Base Plate (Material: FR4 Epoxy Glass Fiber PCB; Processing Technique: Pressing Molding)

5. Contact Chip (Material: typically phosphor bronze; Processing: silver electroplating)

6. Round Bead (Material: Typically made of stainless steel; Processing: Nickel plating)

7. Crossbow (Material: Bronze; Process: Stamp Molding)

8. Decorative Oil (Material: A type of red or green chemical oil, applied to the contact area between terminals and the base plate for decorative purposes. Generally required to be non-toxic and environmentally friendly.)
