The R18-21A RED is a miniature latching push button switch designed for compact control applications that demand dependable switching performance. It features a round red actuator and solder-lug terminals, making it easy to integrate into PCB assemblies or control panels. This switch uses a latching mechanism (SPST-0-1), which maintains its on/off state after each press-ideal for toggle-based circuits or low-power device control. With a 3A rating at 125VAC, it suits a range of AC-powered applications. Constructed with a copper alloy contact system that's silver or gold plated, the R18-21A ensures excellent conductivity and reliability. It provides solid electrical endurance with a minimum of 30,000 cycles and a mechanical life of at least 50,000 actuations, all while withstanding demanding environments thanks to its strong insulation and dielectric properties.
