Electronic & Electrical Spring Solutions
Micro-precision springs, electrical contact springs, and gold/silver-plated components engineered for stable contact resistance and high insertion cycles.
Electronic Industry Spring Requirements
The electronics sector demands ultra-miniaturized form factors, milligram-level force repeatability, exceptional electrical conductivity, and oxidation resistance. TOSTA produces micro springs down to 0.05 mm wire diameter, offering specialty contact alloys (beryllium copper, phosphor bronze) and reel-to-reel gold, silver, or nickel plating to eliminate contact impedance and ensure flawless signal and power transmission.
Typical Applications
Micro Switch & Tactile Button Springs
Provides crisp tactile feedback, clear click-ratio consistency, and exceptional switching endurance exceeding 500,000 cycles.
FPC & Board-to-Board Connector Springs
High-conductivity micro contact springs maintaining stable, ultra-low milliohm contact resistance in compact electronic housings.
Relay & Contactor Armature Springs
Rapid return springs featuring tight force tolerances and high dynamic fatigue life for automotive and industrial relays.
Battery Terminal & Pogo Pin Springs
Gold-plated and silver-plated spring probes providing dependable electrical conduction, corrosion resistance, and high insertion life.
Smart Wearables & Antenna Springs
Micro helical and torsion springs for earbud charging cases, smartwatch hinges, and RF antenna grounding contacts.
Automotive Sensor & Micro-Motor Springs
Vibration-resistant micro springs for throttle position sensors (TPS), micro-brush assemblies, and brake pedal angle sensors.
