OONO DPST 1NO 1NC 8Amp Latching Relay Module (DC 12V)

It's hard to find true latching relays. I used the 12v version to convert my Casablanca Inteli-Touch fans to Wi-Fi smart home controls. I needed a latching relay that would latch to either the forward or reverse motor winding and NEVER both. It would have been great if this module included Wi-Fi and Tuya but I needed an MHcozy switch for that. The MHcozy switch does a one second inch to either the blue lead or green lead on the relay module to toggle and set the fan direction wirelessly. It works great and is especially awesome for my master bedroom fan that is 14 feet high and would otherwise require a ladder to physically switch the fan blade direction. This would be a 5-star review except that one of the four I purchased was bad. It worked on my workbench and then failed almost right away after the fan was mounted. it latched permanently to one of the leads. This forced me to pull the fan down after I had just finished hanging it. The others have worked flawlessly for almost six months now. My only other complaint is that the trigger wires are a very small gauge. That's fine for a 12v signal but too small to work with comfortably and makes it difficult to attach wire nuts securely. Just a minor complaint though.

Bench tested the unit with a 12v power supply. The set and reset relays would activate normally when the red buttons are pushed but not when voltage is applied to the set/rst lines. Very disapointed.

Works as described. No issues.

Draws no current after initial set-reset pulse. Keeps state even after supply power is removed. Draws 50 MA during momentary positive pulse. Small compact size. Works great.

Product works. Don't know how long it will last kinda lightweight. Needed a little more instruction but once figured out worked as it should. Not weatherproof so mount accordingly. Will buy again .
