Make a machine power up with a clack
A relay bank clacking on the frame the switch is thrown gives the power-up its weight, in a sci-fi film, a factory game or an animated lab scene.
Edit prompt
Relay
The dry click of a relay closing, a whole bank clacking in sequence and the heavy thud of a contactor pulling in. Describe the relay sound your scene needs and Morphic generates it clean.
- A single relay click, a clacking bank or a heavy contactor, exactly as asked
- Clicks wired to the moment your machine powers up in the control room
- Clean, isolated audio to drop under a power-up, a console or a lab rig
Relay sounds for games, animation, and video edits
Single relay click
Two dry clicks as a small relay closes and opens, for a circuit board, a device switching mode or a hidden trigger.
Relay bank cascade
A row of relays clacking one after another, for a machine coming online, an old computer booting or a lab powering up.
Contactor thud
A deep clunk and a short buzz as a big contactor pulls in, for heavy machinery starting, a power plant or a crane.
Control box tick
A steady dry tick of a timing relay, for an irrigation box, a traffic signal cabinet or a machine waiting to fire.
Chattering relay
Rapid buzzing clicks of a relay fluttering on a weak supply, for a fault, a failing power grid or a robot glitching.
Panel switching off
Three heavy relays clacking open one after another, for a shutdown, a power cut or the end of a night shift at a plant.

Ways to use a relay sound effect
Hold a tense wait with no music
A control box ticking steadily carries a long, quiet shot of someone waiting, keeping a thriller, a puzzle game or a podcast scene on edge.
Edit prompt
Put the viewer inside a plant room
A heavy contactor thudding in under the opening shot tells the audience they are among big machines, in documentary video, games and audio stories.
Edit prompt
Hint that the power is failing
A relay chattering behind a wall suggests the system is about to fail without showing the fault, useful in horror video, survival games and audio drama.

FAQs
What is a relay sound effect?
It is the click or clack of an electromechanical relay, a switch moved by a small electromagnet. Small relays give a dry tick, banks of them clatter in sequence and heavy contactors land with a solid clunk, which is why they sound like machines waking up.
Where can I get relay sounds for a video?
Generate them from a prompt. Describing the relay you want takes less time than searching a stock library, and you get the exact click or cascade your shot needs. Every sound on this page was made from the prompt printed beside it, so you can start from one and adjust it.
How do I make a custom relay sound effect?
Describe the size of the relay, what it switches and whether it clicks once or keeps going, then generate it. A prompt like "a bank of relays switching in sequence, a quick run of sharp metallic clicks" gives Morphic enough to work with.
What is the difference between a relay, a contactor and a light switch sound?
A relay is a small dry click from a switch moved by a magnet. A contactor is the same idea built big for heavy power, so it lands with a deep clunk and a buzz. A light switch is flipped by hand and has a plastic snap.
Can I use these relay sounds commercially?
Yes, audio generated on paid plans can be used commercially. See our terms for full licensing details. Because each sound is generated for you, you also avoid the clip turning up in someone else's video.
Why does my relay sound not sit right in the edit?
Usually the clicks do not match the lights or dials changing on screen. Line each click up with a light coming on, and for a power-up let the cascade run just ahead of the hum so the machine sounds like it is starting.
