Low voltage relay switch (trigger under 2.5volts)?
I am trying to increase the voltage in an RC boat to produce more speed by using a relay to isolate the motor circuit. The voltage that comes from the original circuit is about 2.5 volts. Does a relay exist that can trigger at 2.5 volts or less?
what i’ve actually done is add another circuit into the boat, the weight isn’t too much, and whats happening is i want the 2.5 volt relay so that i can have the switch between the 2 different circuit, because i’m afraid that the receiver for the RC will short out with so much voltage, therefore i’m using the 2.5 from the original to run the RC part, but a relay added in there to switch the circuits and have the 9v battery i have added with the new 9V motors, (there are 2 separate motors for each propellor). The question was just if anyone knew of a 2.5 volts or lesser relay trigger because the lowest one i found was 5V at radio shack, and can’t seem to find any online less than 5Volts…..

Does anyone have a copy of the RC Cola Sports Fishing commercial?
I forget when it aired, but it featured two sports fishing boats (Coke vs. Pepsi) duking it out in a deep sea fishing tournament. The only thing is they’re catching people. It was pre-CG and they went all out with the live stunts. Anyways, I can never find a copy to explain what I’m talking about when describing it.
