The IPR3FAD6L0S is a round illuminated pushbutton switch with flying lead terminals designed for harsh environment applications. It features a 12 mm bushing diameter with a curved, shiny round actuator and normally open (NO) electrical function. The switch is sealed to IP67 and IP69K standards, with a flat round actuator suitable for optional marking. Key technical characteristics include a maximum current/voltage rating of 100 mA at 30 VDC, an initial contact resistance of 100 mO maximum, and insulation resistance of 1 GO minimum at 500 VDC. The LED component (Super red L0S) operates at 20 mA forward current with a typical forward voltage of 2.1 V and maximum of 2.3 V. This switch is ideal for control panels and harsh industrial environments where reliable tactile feedback and visual indication are required.
