Митко Posted June 23 Share Posted June 23 This is a water pump control box with a double pole switch and an overloading protection with a reset button. The mechanical switch should remain functional. The shelly has a single relay for L. What to do with the N? Can I bridge the N over the switch, i.e. to turn the double pole switch to a single pole switch. Will this cause any troubles with the pump? Or any other idea? Thanks! Quote Link to comment Share on other sites More sharing options...
Heinz Posted June 25 Share Posted June 25 For this i would use a Shelly 1 as it is a Potential free contact relay have a look at the wire diagram for more information https://kb.shelly.cloud/knowledge-base/shelly-1-gen3 if you have questions after looking at the wiring diagram I'm sure we can guide you here Quote Link to comment Share on other sites More sharing options...
SaschaBr Posted July 19 Share Posted July 19 Did you want to bypass the main-switch? This should not be a good idea and maybe a security risk. Maybe you can install the shelly in row to „L“ after the main-switch. Quote Link to comment Share on other sites More sharing options...
