ELECTRONICS-SALON DPDT Signal Relay Module, 24Vdc, RY24W-K Relay. Has Assembled.

I needed a relay to switch a stereo audio signal on and off for a Christmas light show. I initially tried a pair of basic power relays but the sound quality really suffered. This performered perfectly and switches but channels with one relay. Build quality is great and reliability has been solid so far.

There was nothing about this relay board that I disliked. The price, dimensions, power consumption, and design were perfect for my application of building a power on/off latching relay for a DP momentary push button switch off = NC; on = NO.The circuit design is glitch free since it utilizes a transistor buffer to activate the relay and the current draw is in the low milliamp range. The quality of the board etching, soldering and components are very high. A recommended buy.

I used this relay as part of a control system for a linear actuator inside an end effector for a senior design project. It worked as expected. I'm giving it four stars since the two pin terminal block loosened up. We were fairly hard on the part during testing, so it shouldn't be an issue for most users

For some reason I had a hard time getting one of these, specifically to reverse polarity for an actuator. Power on, it extends, power off, it retracts (or visa versa). This little gem works perfect. Well priced, well put together.

Works correctly, maybe a better relay. I replace the relay with a better relay. These relays don't like to be powered for long, the contacts stick closed and after the relay cools the will open eventually. The MFG specs for the relays do suggest these are for switching only, not continuous duty.

Good stuff, I use it for science and drop it sometimes but it hasn't failed me yet. Will probably buy more from this seller since the raw parts aren't even that much cheaper than this and it's a way better soldering job than I can do.

I am using these to control a 12v linear actuator via an ESP8266-01 WiFi board. So far it has performed exactly as I had hoped. Easy to hook up. Reasonable power requirements. Can't complain about anything.
