DESCRIPTION

3U0210000 is a compact pushwheel switch from the 3U Series designed for space-constrained applications in computer peripherals, test equipment, and instrumentation. The switch features a tiny form factor with 10 and 16 position models available, snap-in front mount for simplified assembly, and optional ESD clip protection on select configurations. Electrically, it supports continuous carry current of 1 AMP, operates across 50 mV to 28 V DC with a maximum switch rating of 0.4 VA at 100 mA and 28 V DC, and delivers 1,000,000 actuations of electrical life with contact resistance below 300 mO typical at 2–4 V DC and 100 mA. The housing is constructed from polyester (UL 94V-0) with gold-plated rotor contacts and hard gold-plated stator contacts on epoxy fiberglass, ensuring reliable performance across the operating temperature range of -10°C to 65°C. This combination of compact size, robust construction, and reliable electrical performance makes it ideal for applications requiring durable position selection in confined spaces.
