The IBR3SAD300 is a sealed momentary pushbutton switch from the IB series featuring a 12 mm snap-in bushing design with curved actuator and solder lug terminals. It provides IP67 front panel sealing according to IEC 60529, ensuring protection against dust and water ingress in harsh environments. The switch delivers tactile feedback with a typical operating force of 7 N ± 3 N and a total travel of 1.9 mm ± 0.3 mm, supporting panel thicknesses from 0.8 mm to 1.8 mm. Electrically, it is rated for 400 mA at 32 VAC, 100 mA at 50 VDC, or 125 mA at 125 VAC, with an electrical life of 500,000 cycles at full load and initial contact resistance of 50 mO maximum. The switch is constructed from thermoplastic UL94-V0 case material with silver gold-plated contacts and operates reliably across -40°C to +85°C, making it suitable for industrial control panels, machinery, and sealed enclosure applications requiring robust, long-life switching performance.
