NKK Switches Process Sealed Ultra-Miniature SMT Toggle G3T28AB

The G3T Series consists of process-sealed, ultra-miniature surface mount toggle switches designed for low-voltage, low-current logic-level circuits. The switches feature gull-wing terminals, a 28° angle of throw, and a fully sealed construction with nitrile butadiene rubber seals and epoxy-sealed terminals to enable automated soldering and cleaning. The actuator, case, and base are made of polyphenylene sulfide (UL94V-0), with phosphor bronze contacts plated in gold. They offer a contact resistance of 80 milliohms maximum, insulation resistance of 500 megohms minimum, and a dielectric strength of 500V AC for one minute. Operating temperature ranges from -30°C to +85°C, with a mechanical and electrical life of 50,000 operations minimum. The unit weighs 0.6 gram and supports tape-reel and stick-tube packaging compliant with EIA-481-D. The G3T28AB part is a DPDT switch with a momentary ON-OFF-ON circuit and gull-wing terminals for upright mounting with bracket, fitting the series' general specifications.
