User Documentation


The Mains Switch Solid State Relay allows the user to switch 230V or 110V mains ON and OFF to mains powered devices from micro-controllers like the PIC and the Arduino or from single board computers like the Raspberry Pi and the Beaglebone. All the safety requirements are designed-in to prevent any faults resulting in a fire.


Use 5V or 12V for switching. The 12v trigger from an amplifier can be used to switch on an external power amp.


A plastic enclosure is available to prevent the user from accidentally touching the mains voltage. The user has to supply and wire in a suitable mains extension cable. If you require the plastic enclosure as well please order the Mains Switch Widget.


* Uses Solid State device for switching 

* Electrical isolation (4kV) between the control side and the mains voltage

* Protected by a 5A fuse in the product - to protect the PCB tracks from overheating if there is a fault with the load

* Cable ties to prevent the mains cable pulling out

* LED indication of ON and OFF states

* Can be configured for most parts of the world by using a suitable mains extension lead (not supplied)
