C&K Components, a supplier of tact switches, toggle and rocker switches, and smart card interconnect devices, has developed a series of surface mount jumper DIP switches that are sealed with a removable top tape to enable them to be used in reflow soldering and washable assembly processes.
The TDD Series DIP switches are RoHS-compliant SPDT (single-pole, double-throw) jumpers designed for surface mount PCB soldering, and feature a unique bifurcated contact design that increases electrical reliability. Contacts are constructed from copper alloy with gold plate over nickel plate, and are rated for 25mA @ 24VDC (switching) and 100mA @ 50VDC (steady state), with an operating force of 4.9N (max) and an operational life of 200 cycles. Operating temperature range is -30°C to 85°C.
“The process-sealed TDD Series jumpers enable these DIP switches to be used in reflow soldering processes that require a post-solder washing step,” said Owen Camden, Business Development Manager at C&K Components. “They are ideal for use on surface mount PC boards in handheld electronics, portable computers, instrumentation and control systems, as well as inverters.”
The TDD Series DIP switches are available in 1,000-piece tape-and-reel packaging.
