This is a simple clap switch circuit with high sensitivity. The only unusual component is the single coil latching relay. While there are numerous means of generating the latching function, the ...

This circuit is powered using a 12 volts DC power supply , so the relay used for this project must be a 12 volts relay . This circuit is working very simple , when both plates of the sensor are ...

The relay-actuation side of the circuit needs only a small amount of current, so you can use a low-amp switch and small-gauge wire (even on long runs) to hook it up to the relay.

Meanwhile, relay modules or relay boards are circuit boards that come in many different sizes and shapes. Most of them are rectangular, with 2, 4, 8, or 16 relays mounted. Relay boards include ...

The Relay also requires the presence of a neutral wire in the junction box, which is not a given—especially in older homes. Finally, the existing switch can’t be wired to an AC outlet.

This circuit uses electromechanical relays to retain its state indefinitely, ... When operated at 12 V dc, the circuit shown can toggle as fast as you can tap switch S1.

The circuit presented here (Fig. 1) takes the same power-reduction principle to the next logical level by eliminating the series voltage-dropping resistor and replacing it with efficient switch-mode.

Toshiba's second product in Smart Motor Control Driver SmartMCD™ series delivers integrated solution for automotive brushed DC motor control.

We frequently get home automation tips, many of which have simple circuit-based on/off control for lights. [Paulo Borges] has created something quite different, however, with his in-the-wall servo-… ...
