Alright I am almost ready to go. Just need to work out whether I need to extend the float switch wires, hoping not to avoid having to get a soldering iron and heat wrap!
So to confirm my floatswitch setup.
2x NO switches in the bracket, fitted to the sump return area. Normal water level should be at the top of the bottom switch, so when the water falls the switch opens and starts the pump. Top NO switch is a backup in case the bottom one sticks, so if the water level covers the top switch it will close and stop the pump.
1x NC switch in the reservoir, if the water falls below this switch then the circuit is broken and pump can't start. Any tips on how to hold this switch, given the bracket is for the sump?
Next challenge is the acrylic bracket ...
firechild tips on bending this? Need to heat it first, if so how - just naked flame?
