ELECTRONICS: Electronic components distributor Digi-Key Corp. is now stocking C&K Components’ ELUM Series switches. Designed to eliminate the need for separate LEDs and light pipes on printed circuit boards, these switches feature a 6 mm profile and are available in through-hole and surface-mount configurations. The ELUM features silver- or gold-plated contacts that range in ratings from 0.01 to 250mA and from 20mV to 50V dc. The latching version (push-push) can be specified for switching functions such as mode select and power on/off, while the momentary version is ideal for test, reset and notification functions. The ELUM Series device is one of the only push-button switches designed so the LED travels with the actuator, ensuring even distribution of light. The compact design saves space on the PC board, enabling product miniaturization and greater onboard functionality. ELUM Series switches are RoHS-compliant and compatible with high-speed reflow soldering processes. The 30,000-cycle life expectancy makes the push-button devices ideal for telecom, industrial, medical, automotive and consumer electronics applications.
