It is a switch in the Vcc line to the little power amplifier TA7222ap.

I think the circuitry before it only turns on once the power supply has reached a chosen voltage, and I think that once on, the supply to the TA7222ap is at a reduced voltage compared to the incoming supply. As for why? the answer must be on the rest of the diagram.

Weird!
