PVT4FW4SS341 is an illuminated pushbutton switch featuring a SPST OFF-(ON) momentary contact configuration with integrated blue LED illumination. The switch is constructed with stainless steel actuator and housing materials, providing durability and corrosion resistance in demanding environments. It is rated for 50 mA at 24 VDC with silver contact material, achieving 500,000 make-and-break cycles at full load, and offers an insulation resistance of 1000 MO minimum and dielectric strength of 250 VAC for 1 minute. The switch operates over a temperature range of -25°C to +55°C, features IP65 ingress protection, and includes a 0.5 mm travel distance with M19 × 1.0 thread mounting. This switch is ideal for industrial control panels, machinery interfaces, and applications requiring reliable momentary switching with visual feedback through LED indication.
