Surface-Mount DIP Switch - C&K Components


C&K Components has developed an ultra-miniature, surface-mount DIP switch that delivers consistent electrical performance and high reliability. The half-pitch TDA Series DIP switch features bifurcated contacts that provide increased electrical reliability when compared to other contact technologies.  In addition, the switches are process-sealed for both surface-mount soldering and washable-processing, making them ideal for hand-held electronics devices, portable computer devices, and instrumentations and controls. 

"C&K has made the investment to enhance and expand our DIP switch product offering, delivering new switch features and options that provide design engineers with flexibility when specifying a DIP switch for a particular design," said Owen Camden, business development manager at C&K Components. The RoHS-compliant TDA Series is available in two termination styles, S-termination (Gullwing) and J-termination (Bend).  

The single pole, single throw (SPST) DIP switch is available in multiple positions, including 2, 4, 6, 8 and 10 positions.  The TDA Series DIP switch features a contact rating of 24 V DC, 25 mA (switching state) and 50 V DC, 100 mA (steady state). Operating temperature ranges from -40ºC to +85ºC. The TDA Series switches are available in tape and reel or tube packaging.
