Different switch symbols in circuitikz?

Question

I'm wondering if there are other commands associated with the switch symbol so that one doesn't have to specify if the switch is open or closed. I would like the switch symbol with two connectors and a line rather than the open switch (ospst) and closed switch (cspst). I've looked all over and can't seem to find any solution. Thanks

The following code is a modification of the definition of cspst. I just removed the arc and the arrow.

\documentclass{minimal}
\usepackage{circuitikz}

% modified code from pgfcircbipoles.sty and circuitikz1.code.tex

\makeatletter
% create the shape
\pgfcircdeclarebipole{}{\ctikzvalof{bipoles/interr/height 2}}{spst}{\ctikzvalof{bipoles/interr/height}}{\ctikzvalof{bipoles/interr/width}}{

    \pgfsetlinewidth{\pgfkeysvalueof{/tikz/circuitikz/bipoles/thickness}\pgfstartlinewidth}

    \pgfpathmoveto{\pgfpoint{\pgf@circ@res@left}{0pt}}
    \pgfpathlineto{\pgfpoint{.6\pgf@circ@res@right}{\pgf@circ@res@up}}
    \pgfusepath{draw}   
}

% make the shape accessible with nice syntax
\def\pgf@circ@spst@path#1{\pgf@circ@bipole@path{spst}{#1}}
\tikzset{switch/.style = {\circuitikzbasekey, /tikz/to path=\pgf@circ@spst@path, l=#1}}
\tikzset{spst/.style = {switch = #1}}
\makeatother

\begin{document}

\begin{circuitikz}
    \draw (0,0) to[switch, l=$t_0$] (2,0)
                to[spst] (2,-2);
\end{circuitikz}

\end{document}
