Single Pin Touch Spring 304 Stainless Steel Nickel Plated Micro Capacitive Touch Spring 0.7mm Wire for Electronic Touch Control Components

Our single straight pin touch spring is a precision custom formed elastic component made of premium 304 stainless steel wire. The raw stainless steel wire with 0.7mm diameter is auto-formed into a 5-turn touch spring structure with an integrated straight pin extension on one end, specially designed for capacitive touch signal transmission.

After touch spring forming, every product passes ultrasonic degreasing cleaning to fully remove processing oil and impurities, then undergoes uniform nickel electroplating treatment. The nickel plating layer improves surface hardness, anti-rust performance and conductive stability, effectively preventing oxidation during long-term touch signal sensing service.

As a reliable spring manufacturer, we deliver full OEM custom service for this single pin touch spring and all other micro capacitive touch springs.

This custom single pin touch spring is widely adopted across civilian electronic and precision light industrial industries:

• Consumer small electronic touch panel internal conductive elastic parts
