Some components in Circuitikz use nodes intead of path decorations, so transforming them with invert or mirror does not work. For example, the spdt switch in the image always has its single wire side on the left, even if the whole image is flipped using xscale=-1 as a tikzpicture environment property.
Example code:
\begin{circuitikz}
\draw (5, 0) to (0, 0) node[spdt] {};
\begin{circuitikz}
