12V Switching 40A High-Power Relay

While prototyping your own circuits or working on your automobile electronics, experienced Makers will often reach for a reliable relay to complete the project. Switching relays are ideal for integrating into a project and can be utilised for automobile headlights, air conditioners, and other equipment. Relays are great within a single circuit or multiple coupled circuits. This 12V Switching 40A Relay withstands high power and an impressive switching capability, with a panel mount.

Typically, relays are used to ensure that users and components remain safe from high current leakages or faults, and isolate a circuit from both the user, as well as important parts within a system. Relays like these can also be used as safety mechanisms within a system, which essentially cut off the power or disable a specific part of a system in case of fault, leakage or other dangerous incidents. This can protect important electronics components and ensure that the user is never exposed to potentially harmful currents or voltages.

Typical Applications for 12V Switching 40A High-Power Relay:

While many of our other relays come as modules, attached to a PCB with all of the necessary components and connectors pre-soldered, our 12V Switching 40A Relay is a single unit which is able to be installed wherever you need it in your project. This provides diversity in functionality, as you can use it as a switch, an actuator or as a safety mechanism within a circuit. The lack of extras also means this component costs substantially less, and if you are an experienced Maker who already understands how to utilise relays effectively and safely, then this is a great investment for your home electronics projects.
