12MM metal push button professional introduction

The 12MM metal push button is a precision electro-mechanical component, distinguished by its 12mm mounting diameter and metal (stainless steel, aluminum alloy, zinc alloy) actuator/housing. It is engineered for space-constrained, high-reliability applications, outperforming plastic alternatives in harsh environments.

Core Technical Features

Mechanically, it offers a long operational life (50,000–100,000 cycles) via wear-resistant metal actuators, with actuation force ranging 150–500g for consistent tactile feedback. Environmentally, it withstands -40℃ to 120℃ and achieves IP65/IP67 protection via silicone gaskets, resisting dust, oil, and water ingress—critical for industrial/automotive use. Electrically, silver-alloy contacts ensure low contact resistance (<50mΩ) and arc suppression, supporting rated voltages (250VAC/36VDC) and currents (0.5A–5A) for both signal and power circuits.

Key Classifications & Professional Applications

Classified by function: Normally Open (NO) for momentary triggers (e.g., machine start), Normally Closed (NC) for emergency stops, and illuminated types (LED-integrated) for status indication (red=fault, green=normal).

Professional use cases include: Industrial control panels (CNC machine start/stop), automotive interiors (window lift switches, adhering to AEC-Q200), outdoor EV chargers (weatherproof operation), and medical devices (diagnostic tool triggers, meeting ISO 10993 biocompatibility for metal parts).

Selection Criteria

Professionals prioritize: Contact material (AgNi for arc resistance),  (IP67 for outdoor), electrical parameter matching (avoid overload), and certifications (CE, ROHS, UL) to ensure compliance with industry standards.
