ahblur 0 Report post Posted March 4, 2007 hi... for my case, i change all switches to DS... and was quote about 400 for 13/14/15 switches.. and the orginal switches given by HDB was legrand... which the eletrician say is more ex... normally only Condo will be giving this kind of switches.. not sure it is true.... So come up it cost about 30 plus... But he did mention that water heater switches cost more... 2 can come up to 100 plus... not only the switches also the installation fees.. and cost of the workers... doing the work for u... think should be like this... !!
