Many thanks for conformation that the brake lights are not wired through the ECU Heinz, It is good to know that some of my logic might still be applicable on occasion, though with aircraft falling out of the sky because a whole team of " expert" programmers and others "never thought of that" entirely flawed sequence of operation.....!!!
Except on the 3.7 Roadster which has only one brake switch to operate lights and provide a trigger to PCM.
Regarding the type of switch that Heinz was considering, if used solely to provide an ECU trigger, it could be either NC or NO depending on the expected logic.
Richard thanks for the heads-up on the 3.7 Roadster`s ECU dependant brake light operation... No real surprises there then..Call it evolution Shrug..!
Logically, as an input device a designer can select either NO or NC, though replacement of any such switch in a system the choice must be on a like for like basis.
