Circuit Diagram in Tex with OTE and PILOT Light Symbol

Here is my attempt using TikZ and Circuitikz as suggested by @Rmano.

• Circuitikz package is used only to add capacitor elements, it loads TikZ package.
• arrows.meta library is used to create OUT element.
• shapes library is used to add cross shape to the PL element.

Here is the corresponding code (not an optimized version):

documentclass[border=0.2cm]{standalone}
usepackage{circuitikz}
usetikzlibrary{arrows.meta,positioning,shapes}
begin{document}

begin{tikzpicture}[thick]
ctikzset{
capacitors/scale=0.7,
capacitors/thickness=0.8,
 }
draw (-4.5,2.5) node[above]{$L_1$} -- ++(0,-5);
draw (-4.5,2.2) -- ++(0.75,0)node{$bullet$} -- ++(45:0.5) node[midway,below=0.2cm]{$I/1$}
++(0.1,-0.353)node{$bullet$} -- ++(0.25,0) edge[dashed] ++(0.5,0)++(0.5,0.3) -- ++(0,-5)node[midway](a){};

draw (-4.5,0) -- ++(0.75,0)node{$bullet$} -- ++(45:0.5) node[midway,below=0.2cm]{$I/2$}
++(0.1,-0.353)node{$bullet$} -- ++(0.25,0) edge[dashed] (a.center);

draw (a.center) to[C,l=$I/1$] ++(2,0)to[C,l=$I/2$] ++(1.5,0) coordinate(b); 
draw [-{Parenthesis[reversed,scale=3]}] (b) -- ++(0.25,0) node[right=-0.2cm]{OUT} node[above right=0.2cm and -0.1cm]{$O/2$} ;

draw [{Parenthesis[reversed,scale=3]}-] (b)++(0.9,0) -- ++(0.75,0) coordinate(c);

draw (c) -- ++(0,2.5)
(c) -- ++(0,-2.5)
(c) -- ++(1.95,0) coordinate(d)
-- ++ (0,2.5) node[above]{$L_2$} 
(d) -- ++(0,-2.5);

path (c) -- (d) node[midway,cross out,draw,minimum size=0.8cm]{};
path (c) -- (d) node[midway,circle,draw,fill=white](PL){PL};

draw[dotted,white] (c) -- ++(0.25,0);

node at (-3.55,3.25){Input};
node at (3.55,3.25){Output};

end{tikzpicture}

end{document}

which yields:
