The 302319000 is a PHA Series short stroke pushbutton switch designed for low-cost, reliable switching applications. It features momentary or push-push latching action with 2 or 4 pole changeover contact configurations, sealed contacts for environmental protection, and optional button styles including indexed, rectangular, round, and square designs in multiple colors. The switch operates at a maximum switching power of 3 W DC and 30 V DC with a maximum switching current of 100 mA DC, providing a contact resistance of 20 mO initial and an insulation resistance of 100 MO. With a total travel of 2.5 mm and an operating force of 170–230 grams, the switch delivers 10,000 cycles of operating life at rated load and operates reliably across a temperature range of -10°C to 60°C. This makes it ideal for computers, peripherals, instrumentation, and measurement equipment where non-power on-off switching is required.
