.... and if Overton's has them for $155... You can find them cheaper... and mostly no shipping charges...
A quick check of E-Bay showed over 1000 entries for "lenco switch", from singles all the up through everything they make. I do quite a bit of supplies and needed hardware for my skiff through E-Bay - and have had great results. Since I'm in hard commercial service that includes most of the stuff needed to keep my skiff running properly, the trailer it sits on - as well as most of my fishing supplies - without ever leaving my house...
I recently laid out over 2k for a 24v troller, onboard charger (PowerMania), Battery Tender switch, quick release bracket for that Terrova, etc. all without leaving my house with everything in hand within four days... Like I said - on E-Bay. You have to be careful who you order from but these days finding what you need, checking prices, etc. all super easy....
You might want to remember as well that electronics are constantly being updated by the folks who make them.... Looking for a 2011 switch might not work, but they'll certainly have a currently available switch that will work with older editions of their tabs... I run Bennett tabs and use a control switch they haven't made in many years. Pretty sure I'll have to go with a more modern switch if I need to replace the one I have... Just make sure to make a diagram of the wiring for the existing switch - before you remove it (what color wires go where...). That's info you'll need as you replace it.
