The new JS Series of subminiature DIP switches consists of RoHS-compliant devices in through-hole and surface-mount configurations. Available in four or eight positions, these end-to-end stackable devices offer a sliding twin contact mechanism with self-cleaning action. This feature is said to ensure smooth actuation and high-contact reliability. Gold-plated contacts prevent oxidation and sulfide effect and ensure stable contact resistance. The cover and base consist of self-extinguishing UL94V-0 certified material to ensure high arc and insulation resistance. The subminiature JS through-hole model features terminal spacing that conforms to a standard 0.100 x 0.100 in. (2.54 mm) PC board grid. The terminals are slanted to ensure secure PC board mounting and prevent dislodging during wave soldering. Engineers can choose either top actuated or piano actuation options. The through-hole version features stick-tube packaging. The subminiature JS surface-mount model features gull-wing terminals to ensure secure PC board mounting and prevent dislodging during vapor phase and IR convection reflow soldering. Its terminal spacing conforms to a standard PC board grid with either 0.1 in. (2.54 mm) or 0.050 in. (1.27 mm). Engineers can choose either extended or flush actuators. Stick-tube or tape-reel packaging is provided, depending upon switch configuration. Both versions are rated at 25 mA @ 24 VDC.
