ISR3SAD900 is a sealed momentary pushbutton switch from the IS series, featuring a curved actuator with solder lug terminals and a threaded bushing design for secure panel mounting. The switch is sealed to IP67 according to IEC 60529, providing protection against dust and water ingress, with a compact design incorporating tactile feedback and a 12 mm threaded bushing. Electrically, it supports a maximum rating of 400 mA at 32 VAC or 100 mA at 48 VDC, with an initial contact resistance of 50 mO maximum and an electrical life of 500,000 cycles at full load. Mechanically, the switch offers a total travel of 1.7 mm with a typical operating force of 4 N, and achieves 1,000,000 cycles of mechanical life, operating reliably across temperatures from -40°C to +85°C. This switch is ideal for industrial control panels, instrumentation, and applications requiring sealed, reliable momentary switching with excellent environmental resistance.
