Double action - Double throw waterproof rocker switches
These large waterproof rocker switches act as two double action switches.
They have six pins at the rear three down the left side and three down the right side. The centre pin ( in both cases ) is the live feed. Then the top pin and bottom pin are activated depending on which way the switch is pressed.
Let me give you an example of how these switches could be used.
I have two bilge pumps both are three wire pumps ( Live - Negative - Automatic ) I want to one from my domistic battery and the other from my starter battery.
I want the - switch to be pump on and = to be pump automatic.
I Run a live from each battery to the centre pin.
I run a wire from the bottom pin on each side to the live of my pumps.
I run a wire from the top pin to the automatic on each pump.
I run a wire from each pump to the negative of the correct battery.
