IPR3FAD3 is an illuminated round pushbutton switch designed for harsh environments with a 12 mm bushing and momentary operation. It features flying lead terminals (AWG20, 0.6 mm² section) with standard wire colors: black for NO contact, red for LED anode (+), and blue for LED cathode (-). The switch is sealed to IP67 and IP69K standards, offers tactile feedback, and supports multiple LED color options including super red, yellow, green, blue, white, and dual-color configurations. Electrical specifications include a maximum rating of 5 A at 28 VDC (70,000 cycles for function 3), 0.2 A at 48 VDC (500,000 cycles), and 0.5 A at 48 VAC (500,000 cycles), with an initial contact resistance of 100 mO maximum and insulation resistance of 1 GO minimum at 500 VDC. This switch is ideal for industrial control panels, emergency stop systems, and applications requiring reliable operation in demanding environments with visual feedback.
