Apr 27, 2009
C and K Components has developed a series of illuminated pushbutton switches designed specifically for avionics applications.
The PBA series miniature pushbutton switches feature good tactile feel and are ideal for cold lighting and illuminated displays.
The pushbutton switches feature a robust design, including gold-plated contacts, IP64 sealing, and extended life cycles to 1,000,000 rotations.
The PBA series pushbutton switches are available in illuminated and non-illuminated versions, and the illuminated switches are offered with a white, green, yellow-green, amber or red LED.
The PBA series switches feature a plastic housing and cap that meet UL-94 VO approvals.
Actuation force is 5.5N +/- 0.5N, with a maximum force of 80N.
Travel to contact is 1.2mm +/- 0.1mm, with over-travel of >0.3mm and total travel of 1.5mm +/- 0.1mm.
The gold contact material offers a maximum switching power of 1W, contact resistance of <50 ohms and dielectric strength of 500V rms.
Voltage ranges from 20mV to 150VDC, with a carrying current range of 50uA to 250mA, and a switching current of 50uA to 50mA.
Operating temperature ranges from -30C to +85C and bounce time is <3ms.
The pushbutton switches are packaged one by one or by set.
