### ⭐⭐⭐⭐⭐ Great quality for home projects
*by J***! on April 27, 2025*

I know these are likely clones of some other brand, but they are very good quality. I have one in a dog doorbell going on 8 years. I am currently working on mechanizing a double hung window. I worked out how I wanted the logic to flow and got it done in (4) relays rather than getting into a microcontroller-- which would still require output relays. The "S" input is handy as a cancel function. For instance, in my setup, holding a momentary pushbutton for "up" jogs the motor for a short press, but electrically latches after 2 seconds (output feeds the input). Tapping the opposing button ("down"), cancels the call for "up" and jogs the motor "down". And, if held in for 2 seconds, maintains call for down. Of course, there are reversing relays and limit switches involved. Normally closed limit switches break the negative to their respective relays. Delay-off relays provide Cole Hersee style direction control while also functioning as a safety to limit max time the motor can stay on if a limit switch fails. My only complaint with these is that the terminal screws come screwed down snd must be loosened, first, and that sometimes they are overly tight from factory. Never had a terminal fail, though. All connections are solid.
