ZF Button Micro Switch, Solder Terminal, SPDT, 100mA, 250V AC, IP6K7, DC Subminiature DC3C-A1AA

The ZF DC3C-A1AA is a robust button micro switch engineered for precision switching in compact and demanding applications. As part of ZF's DC subminiature range, this micro switch features a SPDT (single pole double throw) contact configuration, operated via a responsive button actuator. The design provides flexibility for both circuit making and breaking, making it suitable for signal-level switching, safety interlocks, and status detection in automation and electromechanical assemblies.

This micro switch is constructed with Polyethylene Terephthalate (PET) and Polybutylene Terephthalate (PBT) materials in the housing, delivering durability and excellent insulation properties. Its electrical performance supports up to 100mA switching current at 250V AC, which suits various low-power and signal circuit requirements. The component incorporates solder terminals for reliable and secure connections, compatible with a range of panel and PCB mounting styles in control panels, home appliances, industrial machinery, and instrumentation.

The IP6K7 ingress protection rating ensures resistance to dust ingress and temporary immersion in water, making the DC3C-A1AA suitable for harsh industrial, outdoor, automotive, and laboratory environments. The micro switch can operate reliably within a broad temperature range from -40°C to 120°C, offering applicability in both cold storage and high-temperature installations.

A mechanical life expectancy exceeding one million operations ensures long service life, reducing maintenance requirements. With compact dimensions of 20mm width, 11.65mm height, and 6.5mm depth, the switch fits easily in densely populated assemblies and modules.

Typical applications for the ZF DC3C-A1AA button micro switch include industrial automation, HVAC and building management, safety and security devices, automotive systems, medical devices, and instrumentation where precise, reliable, and consistent switching is essential. Its construction meets RoHS compliance, assuring suitability for modern, environmentally conscious designs.
