Hey guys I am working on a safety system for the brake system and I am looking for a detent switch that can be used to stop the system from working, ie the engine and fuel pumps an dother electronic controls in the car. The switch has to be SPST and should keep the system 'off' until the reset button is activated. I am not really sure which switch or button to use as I am finding it hard to get anything worth using. Does anyone know any company that can be of assistance in terms of finding a switch to use? Preferably in South Africa. Thanx in advance!
