Illuminated Pushbuttons Suit Avionics Displays
Designed specifically for avionics applications, the PBA Series of miniature pushbutton switches from C&K Components has a robust design that includes gold plated contacts, IP64 sealing, and extended life cycles to 1,000,000 rotations. Actuation force is 5.5 N ± 0.5 N, with a maximum force of 80 N. Travel to contact is 1.2 mm ± 0.1 mm, with overtravel of greater than 0.3mm and total travel of 1.5 mm ± 0.1 mm. Offered with a white, green, yellow green, amber or red LED, the switches are also available in non-illuminated versions. The gold contact material offers a maximum switching power of 1W, contact resistance of =50? and dielectric strength of 500V rms. Voltage ranges from 20mV to 150V DC, with a carrying current range of 50µA to 250mA, and a switching current of 50µA to 50mA.
