When the touch duration is more than 32ms and less than 332ms, the logic control part circuit is in the switching working state. When the touch duration is more than 332ms, the logic control part circuit is in the dimmer working state, the output trigger pulse phase angle continuous cyclical changes between the 41 degrees to 159 degrees, and according to the human eye sensibility, there are three processes: the fast process, the slow process and the intermittent process.
