Treatment: Nickel electroplating or black oxide coating for corrosion resistance
Plastic Actuator
Material: Flame-retardant PA nylon (for high-temp applications)
Process: Injection molding
Terminals
Material: Phosphor bronze
Treatment: Silver plating
Insulating Baseplate
Material: Phenolic laminate
Process: Precision punching
Contact Blades
Material: Phosphor bronze
Treatment: Silver plating (contact resistance ≤30mΩ)
Detent Ball
Material: 304 stainless steel
Treatment: Nickel plating (salt spray test ≥96hrs)
Spring
Material: Beryllium copper (C17200)
Process: CNC stamping (tolerance ±0.02mm)
Decorative Coating
