Thanks for buying an Eggtimer Remote Switch! This is the answer to a problem that has
bugged many of us electronic deployment users for a long time… How do you turn on (and
off) the power to your electronics without opening up the AV bay? There have been all kinds
of switches, both mechanical and electronic, used in hobby rocketry, but they all have involved
having to reach into a hole in the AV bay or put something like a magnet very close to it in
order to turn on the switch. More than once we’ve had to take a rocket off the rail because we
couldn’t reach the power switch inside the AV bay…
The Remote Switch uses a standard generic 315 MHz 4-button remote control to allow you to
turn your electronics on and off from up to 100 feet away (dependent on the antenna, and the
construction of your AV bay). You program your Switch with an 8-button code of your
choice, there are over 65,000 possible combinations; the chance of somebody accidentally
powering on or off your rocket’s electronics is very slim. It can be fed from 6V-20V, and is
capable of handling over 2A continuous or 8A in bursts (i.e. like the spike from an igniter).
We’ve used it to light Estes igniters with a 2S LiPo in testing, so we’re pretty confident that it
can handle whatever your electronics can dish out. Typical draw is only about 15 mA, so any
2S LiPo worth buying is going to last the whole day and then some in your AV bay.
Like other Eggtimer Rocketry products, we sell it as a kit, to keep costs down and provide an
outstanding value. This means that you have to do a little work, of course, but considering that
most hobby rocketeers that would use our products have some degree of electronics expertise;
this should not be much of an impediment. If you do not have any experience soldering kits
such as this, we recommend that you ask around… chances are that somebody in your rocketry
club would be more than happy to assist you for a small bribe (beverages work well!).
