switch on

Flip to engage

To switch on is to activate something by flipping a switch or pressing a button: Switch on the light.

The phrase extends to anything that starts functioning: The heater switches on automatically at six.

Figuratively, to switch on is to become alert or engaged: She really switches on when the topic interests her.
