Using relays for audio signal switching? | DiyMobileAudio ...

I can shield the relay(s) easily enough, but the audio signal will be close to the 12v relay coil no matter what I do. I'm thinking that perhaps the relays need to be transistor based, without mechanical coils, but that's well beyond my skill levels to design. I could build a circuit if I had a schematic.
Using relays in high voltage circuits | diyAudio

Anyone who have any experience about using relays designed for 230Vac use in high voltage circuits. How large voltages can these relays can tolerate, are there any risks about using relays in high voltage circuits? I would like to hear any experience about using relays in high voltage circuits.
How to use relay with schematic of relay circuit diagram

If the relay is not working or not performing the activity then you are using wrong voltage coil. Mostly 12 volt coil is used in relays, but few relays have 5 volt coil. 5 volt coil relays are easy to use, so you don’t need high power supply. Five volt coil relays are easier to use, since you don’t need to a high voltage power supply.

The main usage of the Relay was seen in the history of transmitting and receiving the information, that was called as Morse code where the input signals used to be either 1 or 0, these change in signals were mechanically noted in terms of ON and OFF of a light bulb or a beep sound, it means those pulses of 1s and 0s are converted as mechanical ON and OFF using …

Whilst the common emitter relay circuit will be the most popular, it is sometimes useful to use a common collector or emitter follower configuration for the relay circuit. This relay circuit just replaces the emitter resistor with the relay coil. Again the diode is incorporated into the relay circuit to prevent damage from the back EMF induced at turn-off. The base resistor is placed in …

Also remember that when a relay is rated for say 24V it will work within a range between 17V and 36V (specs may differ). So when you've a +/-18v PSU you may be able to power both audio and relays from it. Unless you're building a complicated device like a mixer or so, I think a separate PSU for relays is overkill.
Introduction to Relay Logic Control - Circuit Digest

Relay logic basically consists of relays wired up in a particular fashion to perform the desired switching operations. The circuit incorporates relays along with other components such as switches, motors, timers, actuators, contactors etc. The relay logic control works efficiently to perform basic ON/OFF operations by opening or closing the relay contacts but it …

With the above the hardware, it would be easy to use the elecrow now. for example, we want to use the relay shield to control the lamp on/off, connect the relays as below: 1. Cut off the power wire of your lamp; 2. Connect on end to the COM1, and the other end to NO1; 3. Ensure the manual control switch on the off side; 4.
