Have you ever needed to power a 12-volt relay in a circuit but only had 6 or 9 volts available? This simple circuit will solve that problem. It allows 12-volt relays to be operated from 6 or 9 volts, ...

Hybrid relays combine a mechanical switch with a solid-state switch, and they are set up in parallel to control a single load ...

A simple and convenient way to interface 2 relays for switching application in your project. This relay driver boosts the input impedance with a regular BC547 NPN transistor (or equivalent). Very ...

An RC circuit in series with the coil allows full-current turn-on for reliable relay operation, then reduces the current to save power. Fellow engineer Sanjay R. Chendvankar of Mumbai, India, recently ...

Designers frequently use special circuits to reduce the power required to hold a relay in the latched position. Analog circuits such as the "brute force" resistor-capacitor solution or the ...

According to a report from Securities Star, data from the Tianyancha APP shows that Xinrui Technology (300745) has recently obtained a utility model patent authorization. The patent is titled 'Relay ...
