Pressure Switch – Part 2

I am having a real hard time getting the pressure switch to be fully air tight. The switch works, but after 20-30 seconds, it stops conducting. I am guessing that there is some tiny air leak which is letting in undetecable amounts of air. I have been unsuccessful in sealing the switch any further.

I will continue to explore ways of making a more sealed switch, but I am also looking into other ways of detecting the end of the booster thrust phase.

  • Pressure – Similar to the current switch I am working on, but with a small switch inside a balloon
  • Temperature – According to Boyle’s law as pressure drops, so should the temperature if the volume of the bottle stays the same. A thermistor should be able to detect this.
  • Water Sensor – Detects when all the water has been expelled from the rocket.
