Product Description

Electrical contact springs with silver nickel contact points are widely used in electrical switches, relays, and power control devices where stable electrical conductivity and arc resistance are required. The spring structure provides reliable contact pressure, while the silver nickel (AgNi) contact ensures excellent electrical performance and long service life.

The base material of the spring is typically phosphor bronze, brass, or stainless steel, manufactured through precision metal stamping. The silver nickel contact is welded or riveted onto the contact area to improve wear resistance, conductivity, and arc erosion resistance.

These components are commonly used in switches, relays, circuit breakers, household appliances, automotive electronics, and industrial electrical equipment. Custom designs can be produced according to drawings or samples.
