A component of a circuit changes, as shown below.

At left a short horizontal line then a small circle with a line pointing up at about 45 degrees then a short gap then a small circle then a short horizontal line. In the middle an arrow pointing right. At right a short horizontal line then a small circle then a shorter horizontal line then a small circle then a short horizontal line.

How would this change affect the electric circuit?

A switch is closed, so the circuit would be incomplete and broken and the lights in the circuit would not shine.
