Achieve max electric fuel pump output and safety using a relay plus an oil pressure safety switch. Achieving maximum output and safety with a custom-wired electric fuel pump requires a properly ...

You hop in your Dodge diesel and turn the key only to be greeted with a click-click sound, instead of the more familiar whirring of your starter motor. Something is wrong. You somehow knew that the ...

Several years ago, Paul Rako, in collaboration with the late, great Bob Pease, wrote a terrific article about the finer theoretical and practical points of electromagnetic solenoid-driver circuits. 1 ...

Solenoids are everywhere. They open the water valve in your dishwasher, control the flow of gas in your stove, regulate ink delivery in printers, and play a crucial role under the hood of your car.

A simple ohmmeter is all that is needed to troubleshoot a potential relay. After taking all of the connecting wires off of the potential relay, measure the resistance across the 1 and 2 terminals. The ...

In electronic and industrial automation systems, relay modules play a crucial role by allowing low-power control signals to switch high-power devices. Selecting between a 5V relay module and a 12V ...

You turn the key on your Jeep and are greeted with a clicking sound, or maybe only silence. Whether you’re running late for work or headed out for weekend wheeling, that’s a situation that can ruin ...

This simple temperature relay circuit can be used to signal a fire or setpoint for temperature monitoring function. You need to adjust P1 so that T1’s base voltage is 0.5V smaller than the emitter ...

Hybrid relays are changing the way we think about switching inside electronic circuits. By combining the fast response of solid-state components with the reliability of mechanical contacts, these ...
