Have you ever required the ability to be able to switch on or off
your engine preheaters at will from almost anywhere? Now you can
with the JoesPiper simplified Cell-Phone Switch Box!
The pics shown below illustrate the first constructed prototype
which has been working flawlessly since its inception.
The Cell-Phone Switch Box can be
plugged into any circuit protected 120v AC socket. The switch box
incorporates a step down transformer to power the circuit board that
operates a 15 amp relay that is turned on or off utilizing the front
light of your cell phone when it is called. There is also a light
bulb socket (738V) that incorporates an E26 - E17 reducer for a C9
bulb (wrapped in tin foil to preclude light) to provide heat for the
circuit board. This particular Cell-Phone Switch Box is setup to
activate on 2 rings, then deactivate on 1 ring.
