How to remove the protrude of the path with arrow?

Question

From this code is from an answer to my previous post. The arrow is nice but if I want to move the arrow to the end of the path by setting mark = at position 1 there is still a protrude part which doesn't look nice.

Is there any idea to remove this part?

\documentclass[tikz, border=1cm]{standalone} 
\usepackage[american, siunitx, RPvoltages]{circuitikz} 
\usetikzlibrary{decorations.markings, arrows.meta} 
\usetikzlibrary{backgrounds}

\begin{document}

\begin{tikzpicture}
\ctikzset{inductors/scale=0.5, capacitors/scale=0.5, sources/scale=0.5, switches/scale=0.5}
\draw  (0,0) coordinate (start)  node[ocirc]{} to [cute open switch]
++(1,0)  to [cute inductor, l^=$L$] ++(1,0) to [short]++(0.5,0) node[ocirc]{} coordinate (end);
\begin{scope}[on background layer, decoration={
markings, mark=at position 1 with {\arrow{Stealth[scale=0.8]}}} ]  
\draw[ultra thick, red!40, postaction={decorate}, transform canvas={yshift=3pt}] (start) --(end);
\end{scope}
\end{tikzpicture}
\end{document}

Answer 1

Normal arrow:

\draw[-{Stealth[scale=0.8]}, ultra thick, red!40, transform canvas={yshift=3pt}] (start) -- (end);

If you for some reason need to do it with a decoration, you need to manually shorten the line like this:

\draw[ultra thick, red!40, postaction={decorate}, transform canvas={yshift=3pt}, shorten >=2pt] (start) --(end);
