What symbol depicts a switch in a TPC schematic?

The symbol that depicts a switch in a TPC schematic is represented by a line that is interrupted or shows a break in a conductive path. This design effectively illustrates the concept of a switch, where the circuit can be either completed or interrupted, depending on whether the switch is open or closed. The break in the line signifies that the electrical path is not continuous, representing the switch in its "off" position. When the switch is in the "on" position, the line appears continuous, showing that electricity can flow through the circuit.

The other symbols listed convey different elements in a schematic. A complete circle typically represents a connection point or a node in the circuit rather than a switch. A dashed rectangle might indicate an enclosure or a specific component, but it does not represent a switch's function. Similarly, a triangle with a breakout is more characteristic of a specific type of electrical component, like a voltage source or a transformation element, rather than a simple switch. Thus, the correct choice of an interrupted line clearly communicates the nature of a switch's operation within a schematic.
