The instructions do not mention anything about the TRIGGER-SW, (below the relay) but after playing around, I have found that shorting the centre pin and the upper pin MOMENTARILY will re-start the timer - either of the poles of the switch will work), (The bottom switch pins do nothing). This is an important omission in the product description and instructions because this means that a remote switch could be introduced to re-start the timer and thus make it more useful in other applications also. Cheers, Derrick

Used as a solar triggered WiFi Daylight control. To reverse the relay operation Just exchange the 5Y3 transistor (NPN) for a (PNP) generic transistor such as a 2n2907. I used an A56. Be sure to exchange the emitter and collector leads.

Ordered 2 modules. Received 2 different modules. One as in the picture, and another one that looks different (not the same PCB). Ordered this modules after I had tested one about a month ago, and it's working fine.

Great universal 12v delay relay. Will switch 120vac. Wide range of delay choices: From a Fraction of second to more than an hour using the jumpers. The device activates the relay at turn on and releases the relay at the end of the delay.To reverse the switching order: Simply change the NPN (J3Y) transistor to a PNP type and reverse the emitter and collector leads. Any generic switching transistor will fit. Works fine for me.
