I’m always trying to scrounge screw terminal blocks for various projects, and finally found my favorites. I use them on my prototype and permanent projects where temporarily sticking a sensor wire into a header is no longer appropriate. These are rated at 8amps up to 250v, so will work great with the many low voltage, low current applications we build. At $6 for 20 two pole blocks (that clip together for more poles) you can’t go wrong!
