Using this adapter is a breeze. First, get your stranded or solid core wire ready. Then, simply lift the little levers on the push - terminal blocks. Slide the wire into the block and let the lever go to secure it. You can quickly assemble your own wiring jigs without the need for soldering. When using it for non - standard wiring setups or connecting to older devices, make sure the pins match up correctly. As for maintenance, keep it in a dry place and avoid bending the pins. If there's dust on it, you can use a soft, dry cloth to gently wipe it clean.
