SA1RV20 is an ultra-miniature normally open pushbutton switch with a round base designed for AC and DC circuit applications. The switch features gold-plated copper contacts and terminals, with a resistive rating of 0.75 amperes at 125 VAC normally open, and 1.0 ampere normally open for 15,000 operations. It has a pretravel of 0.015 to 0.050 inches, overtravel of 0.030 inches minimum, and an operating force of 8 ounces maximum, with 50,000 operations minimum for both electrical and mechanical life. The switch is mounted with an #8-40 nut and is ideal for applications requiring compact, reliable switching in control panels, instrumentation, and electronic equipment where space is limited.
