In my house in Spain, I have just replaced 2 switches that controlled a single motorised shutter (the pair of switches in photos - NB, shutters are the middle of the cluster, other 2 being, 2-pin socket and a light switch) on a bed headboard that controlled a motorised window shutter. The originals were single-button sprung rocker (press and hold to engage) switches (up - (sprung back to) off - down). Leroy Merlin’s own ‘Lexman’ brand’s solution was a prewired 2-switch unit where one was ‘up’ and the other ‘down’; each button has an ‘off’. (This is the large switch with diagonal and short horizontal black cable joining things up with other bits of the switch. Despite being physically able to select both up and down at the same time, the circuit prevents this electrically.
My problem is that while I can make one switch on one half of the headboard work exactly as advertised (up, down and stop), the other makes a whining sound and only drives the shutters down (but not up) at a snails’s pace. No circuit breakers/RCDs blow. I thought that this might be a conflict between a switch set to ‘drive’ on one side of the bed while the other was being asked to go the other way but this still happens if the ‘good’ switch is set to,’stop’ on both it’s ‘up’ and ‘down’ buttons.
Question. How can I wire these switches together (incl the schematic from the packaging) to control the single window shutters from either side of the bed - or is this impossible with this design of switch?
