The 30-2505 is a sub-miniature, single-pole double-throw (SPDT) snap-action switch equipped with a roller lever actuator. It is rated for 5A at 125V AC and 3A at 250V AC, with an initial contact resistance of 15 Meg ohm maximum. The switch features silver contacts, brass silver-plated solder terminals, and has a dielectric strength of 1000V AC for one minute. Key mechanical characteristics include a maximum operating force of 45g, a minimum release force of 12g, and an operating position of 14.5 ± 0.8mm. This momentary switch is suitable for applications requiring a compact, reliable switching component with a roller for actuation.
