Spark 3 Green Connector ID/Source

I’d like to connect an SSR to the Spark 3 (which I have ordered but don’t have yet). Can you give a reference/link/name of the green connector I should get to mate with the four or six pin connector on the Spark 3? Thanks.

The four pin and six pin connectors are considered 2x2 and 3x2 sets of +/- pins, respectively.

As to the connectors, you’ll need @Elco for the name, but we do include 5 of them with every Spark3.

Ah great. That should be good for me for a while. It would be good to have a source, but now isn’t so urgent.

As it turns out, they don’t really have a snappy name. I asked around in the office, and everyone just calls them “those green connectors”. Their official designation is “WR-TBL Serie 3587 2 pins” (

We don’t directly sell them in the shop - the 5 connectors included with the Spark usually are sufficient. If you find yourself needing more, contact us, and we’ll see what we can do.

I had misplaced the extra connectors. Ordered something similar on Digikey.
