| Go-no-Go Switches
are a safety feature needed on all vehicles that have hydrogen generators.
The switch is used as a fail-safe. Normally, hydrogen generators use the ignition
switch to turn the cell on and off. That is fine for normal operation, but
not everyone can avoid getting slapped with the "stupid-stick". That is, we
all make mistakes by leaving the ignition switch "On" at times when the
engine is not running; such as listening to the radio. Should this happen,
your generator continues to make HHO gas. The gas collects in your Air Box,
breather, and engine. If you start the vehicle, it will ignite the gas
buildup --- K-A-Boooom! There will be Damage.
Adding a Go-no-Go Switch causes two requirements
to be met in order to starting your hydrogen generator. The first
requirement is for the ignition switch to be "On". The second requirement is
for the engine to be Running. |

Hobbs M4070-2 Vacuum
Switch
- Normally open. when it senses engine
vacuum of 2"Hg. or more,
- Closes to complete a circuit..
- Very well built; outer casing is composed
of ceramic and metal, not plastic.
- The threading is 1/8" pipe thread.

Oil Pressure Switch
Oil Pressure Switch (or Oil Pressure Sending
Unit): In this case there is a switch that will provide 12 volts when the
engine is running, but if the engine stops, then the switch falls into the
"off" position, which turns off the relay and the fuel pump. In this case
the car's computer must first energize the fuel pump relay long enough for
the car to get started, then it shuts off it's circuit and the Oil Pressure
Sending Unit continues to energize the circuit. |

Electrical Current Sensing
Switch on the Alternator The
Alternator charges the battery only when the engine is running. this sensor
is activated by the current flowing to the battery. It only works on
vehicles that constantly send a charge to the battery. You would use these
switches to activate your Power Relay.
DS1 Series Current Switch
- Reed Switches work, but are not
reliable; they tend to stick.

Air Flow Sensor Switch
Mass Air Flow Sensor: Some vehicles have a
switch incorporated into the Mass Air Flow sensor. In this case instead of
oil pressure, the flow of air into the engine is used to keep a switch on
that powers the fuel pump relay. In all other respects, this type of system
is the same as the Oil Pressure Switch. |

Fuel Pump Switch
Fuel Injected engines are equipped with Fuel Pump Switches
that turn the Pump on when the ignition switch is turned on. The engine has
to have fuel before it can start. Somehow, the electronics sense when the
engine is not running, and the fuel pump gets turned off. It is possible to
use that circuit to turn your HHO Generator on and off. A lot of
experimenters are using it. I never have. |
