The Unionwell G303‑130F00B51J‑FA Push Button On‑Off Switch with right‑side lead wires sets a new standard in small‑switch performance. Its fully sealed housing—molded from durable neoprene or Santoprene—delivers genuine water resistance, protecting internal components in even the harshest environments. Available in both maintained and momentary pendant styles, this switch uses a proprietary production process to achieve exceptional electromechanical performance, an extended temperature range, and cost-effective manufacturing.
At the heart of the G303‑130F00B51J‑FA is Unionwell's patented carrier design, which prevents dust, dirt, and moisture from entering the switch assembly—even when the button is fully depressed. This makes it one of the most rugged subminiature switches on the market. Backed by two decades of custom switch design experience, Unionwell's engineering team can adapt the G303 series to virtually any application, serving as an extension of your product development group to ensure seamless integration and optimal reliability. Whether you need a standard on‑off control or a highly specialized solution, the G303 delivers unmatched durability and precision for automotive, appliance, industrial, and marine applications.
