C&K offers custom snap-on caps for Elum switches

David Webber, worldwide product line manager for C&K Components, comments: "Elum saves a great deal of space on the circuit board, allowing for product miniaturisation or greater on-board functionality. We are able to further increase service and value to customers with our in-house capabilities for tooling the custom caps."

The switch has a low 6mm profile and is available in through-hole and surface-mount configurations. Elum switches feature silver- or gold-plated contacts that range in ratings from 0.01mA 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 suitable for test, reset and notification functions.

Three versions of the Elum cap have been tooled up. The 957C00000 version is a high-temperature black cap that can be installed at the factory or as a secondary operation after the switch has been processed to the board. These caps are capable of withstanding RoHS solder profiles. The 181D series are made out of clear polycarbonate material and paint and laser etched, making the cap easily customisable. The 181D01000 caps are paint and laser etched, and the 181D00000 versions are also paint and laser etched and feature a white paint underlay for increase visibility when the LED is not illuminated.

Elum switches are RoHS-compliant and compatible with high-speed reflow soldering processes. The 30,000 cycle life expectancy makes Elum switches suitable for industrial, telecom, medical, automotive and consumer electronics applications.
