On came the office lights, as some one pressed the switch.

The first was just before he pressed the light switch.

He closed the door behind him and pressed the light switch.

It pressed the light switch at the right of the door.

The door of the room was opening; a hand reached in to press the light switch.

She pressed the switch and turned quickly as the light came on.

The left hand pressed the light switch by the bed.

Then a man by the door pressed the light switch.

Every 10 minutes Eric would get up and press the switch of the master test board.

It seemed to take for ever to press the switch.
