I'm trying to build a circuit with multiple timers, each with an SPST output relay. I want to connect up my circuit so that if any of the timers reaches their set point, they turn on a beacon. It doesn't matter how many timers reach their set point, as long as one has I want the beacon to be on. Additionally each timer will turn on its own light when it reaches the set point.
I've drawn up a circuit, but have a question, is it possible to control two lights with one SPST switch? The simplest form of the circuit I'm visualizing is shown below:
(All the Lights and Beacon and Power Supplies are 12V)
The outsides (including the switches) are the timer circuit section, while the middle part is the beacon and its power supply.
I'm particularly confused about what happens in the red path. Would that be bad for the lights? Or turn them on before the timer switches close?
