I have recently replaced a storage heater and took the opportunity to change the cable and wall socket (the old socket had lost the red cover for the neon light). The replacement wall switch clearly shows the 'on' 'off' below the red indicator light. Having installed the new socket I was surprised to find that once the e7 power came on the indicator light was illuminated whether the switch was set on 'on' or 'off' � this is contra to all the other older switch's � I have checked, checked and checked that I wired the replacement socket correctly.
hi, the lead from the neon must be connected to the live side of the switch. turn the power off at the mains and put the neon lead into the other cable inlet marked " load", (load being the new storage heater ). if the leads are integral and not accessable, then it may be a faulty switch.
