Lynx Anti-Spark Switch

$12.50

Bring some Lynx DNA to your robot! This switch is specifically designed to power on and off your 6s+ robot without sparking or eroding the contacts. On other switches, spark erosion reduces the amount of electrical contact the switch makes, resulting in heat, power restriction, or random switch failures. When you turn your bot on, there is a huge rush of current to charge the empty capacitors. The Lynx Switch has a built-in pre-charge circuit that limits the inrush current when turning on your robot, gently charging up the capacitors in your bot. While this beetleweight switch is designed for 6s and up, it can also be used with batteries less than 6s or for robots smaller than 3lbs or larger than 3lbs at your own risk.

Lynx Switch

Bring some Lynx DNA to your robot! This switch is specifically designed to power on and off your 6s+ robot without sparking or eroding the contacts. On other switches, spark erosion reduces the amount of electrical contact the switch makes, resulting in heat, power restriction, or random switch failures. When you turn your bot on, there is a huge rush of current to charge the empty capacitors. The Lynx Switch has a built-in pre-charge circuit that limits the inrush current when turning on your robot, gently charging up the capacitors in your bot. While this beetleweight switch is designed for 6s and up, it can also be used with batteries less than 6s or for robots smaller than 3lbs or larger than 3lbs at your own risk. 

There are a few important things that make the lynx switch unique. It must be fully unscrewed until it is topped out for the off position. Like normal switches, it must be completely tightened down for the full on position. However, this switch adds an intermediate pre-charge position that it should not stay in for long. The Lynx Switch adds all this capability while only measuring 6x14x14mm. It features an extra-long output tab that acts as a buss bar, large enough to solder multiple wires to.

 

WARNING: Running a bot in the intermediate pre-charge state will burn out the pre-charge resistor. Also, when turning off the switch, unscrew it until you feel resistance. Too much torque in the unscrewed position can strip out the threads.

Assembly instructions:

  1. Remove oxidation from contacts with sandpaper.
  2. Solder the battery negative to the top short tab and insulate the connection.
  3. Solder the wires from the ESCs to the long bottom tab. 
  4. Ensure the screw is unscrewed and in the off position before plugging in your battery.
