IRR3F422 is a sealed illuminated pushbutton switch from the IR series designed for panel-mounted applications with a 16 mm round bushing and momentary action. It features flying lead terminals with integrated LED capability, offering IP67 front panel sealing and tactile feedback with a flat round actuator. The switch is rated for gold-plated silver contacts with a maximum current/voltage rating of 200 mA at 48 VDC (500,000 cycles) or 5 A at 28 VDC (70,000 cycles), with an initial contact resistance of 100 mO maximum and dielectric strength of 1,500 Vrms. Operating across a temperature range of -40°C to +85°C with shock resistance of 100 g and vibration resistance of 10-500 Hz at 10 g, this switch is ideal for industrial control panels, instrumentation, and applications requiring reliable illuminated feedback in harsh environments.
