Hi all, I had just recently bought the Legrand Mallia switches from Choo Chiang @ Blk 640 Rowell Rd. Choo Chiang are selling the switches at contractor price before GST. I'm a blur sotong, so when i was there.. certain things i need to call back to check with my ID or my dad. So this guy - Derrick is quite nice and patient, he reminded me whether I need the mounting box or not, since I'm buying for myself and also for a friend. So needed both non-conceal box and concealed box. As my dad is an electrician, he told me to write down the type and qty of the switches I need before going there.. since Choo Chiang is supplying to contractors who normally come, list the items they need, pick and go. So the pace they handle contractors are quite fast. My advise is not to get the switches from lighting shops, basically if you buy a 1gang switch, you can use the same amount to buy 2 or 3 from shops that supplies them to contractors. Even Homefix store are selling Legrand switches at a higher price.
