how to make always on?

[winson2769]

hi all , i recently bought a small air purify. that is when press the button first time, it will operate continually air purify, the second time press will operate intermittent and third time will stop device. But i found that it is not convenient for me .Because what i want is when turn on the power supply, the device will auto on without press anything. i dun card is that operate continually or intermittent .Is that possible to do so? thank for reading, hope can get answer.

Welcome to the forum. Try pushing the switch BEFORE applying power and hold it. Then apply power. If it turns on then all you need to do is short the switch. If not, then you need electronics to simulate a button press.
