PV4F2B011-3R4 is an illuminated panel-mount pushbutton switch featuring RGB (Red/Green/Blue) ring illumination and a flat black anodized actuator. The switch employs a single-pole double-throw (SPDT) contact configuration with momentary operation, rated for 2A at 24VDC with silver contact material. It offers robust electrical performance including 50,000 make-and-break cycles at full load, 1,000 MO minimum insulation resistance, and 2,000 VAC dielectric strength for 1 minute. The switch is housed in a black anodized body with M19×1.0 thread mounting, supports a maximum panel thickness of 11.0 mm, and operates reliably across -25°C to 55°C with an IP67 ingress protection rating. With a 2.8 mm travel distance, 12V lamp voltage, and supplied hardware including O-ring and hex nut, this switch is ideal for industrial control panels, machinery interfaces, and applications requiring visual feedback and reliable switching performance.
