| The LDM Series surface mount, IC style DIP switch uses industry standard gull wing style terminals. Insert molded terminals and an ultrasonic welded body enable flux washing the whole switch (if top tape sealed). Gold terminal plating helps ensure an excellent solder bond even after an extended shelf life. Packaging options include tubes and tape and reel for machine placement. You may also be interested in J-bend surface mount (LDJ Series), half-pitch surface mount (LDH Series), and through-hole mount (LDI Series) versions. |
