A triac is a semiconductor widely used in systems powered by alternating voltage.
If simplified it can be considered as a controllable switch.
When it is closed it behaves like an open switch. Control current supply to the triac control electrode leads to its transition to the conducting state.
At such a moment a triac is like a closed switch ...
