I needed a relay to control a low voltage light and had this component sitting about, and its much nicer with these things in enclosures so I made this!

There is a screw mount, a 12mm pipe mount (yes its weird, I needed this one!) and a basic case available. The screw mount option has 5mm holes for the screws to go through.

If you are using this in ESPHome here is an example where I am using it to control LED lighting. Your pin will likely differ.

output:

  - platform: gpio   

    pin: GPIO8

    id: l1

 

light:

    - platform: binary

      name: “LED Lighting”

      output: l1

Required For Assembly

• 6x M2x6 screws
• 3x M2 washers
• 6x M2 Ruthex/CNC Kitchen inserts (plus 4 if using the 12mm pipe mount)
• Soldering iron
• Seeed Grove High Current Relay
• (12mm pipe mount option only) extra 4x M2x8 screws + 4x M2 washers

Due to the depth and position of the M2 inserts in this build it may be easier to use the normal soldering iron tip rather than the proper Ruthex/CNC Kitchen insert tools for the inserts in the bottom of the case.

Do not remix this and put screws or magnets in the bottom. This relay may be potentially running a high voltage. Also magnets may interfere with this mechanical relay.

Assembly

Install all six M2 inserts into the holes in the main body of the case.
If you are using the 12mm pipe mount option install two M2 inserts in either end.
Insert the board in the bottom of the case (note the modelled board pictured does not match it at all).   Secure the board with 3 of the M2x6 screws. Do not use washers, and be careful to not do up the screws too tightly.   Plug the grove cable into the board now.
Thread the cable through the hole in the lid.
Attach the lid and secure it with the remaining M2x6 screws and washers.
If you are using the 12mm pipe option, secure the clips on the end (which also serve for cable management) with the M2x8 screws and washers. Congratulations, you are done!
