@munna master thank you for sharing
do consider editing the title, its mostly regulators only
[dimmers can cause havoc and in simplest of cases; they will hinder a fan from operating properly/ as designed.
dimmers are meant for dimming. and in India we often find ourselves using dimmers meant for lighting equipment or bulbs and tube-lights diverted for use as fan regulators]
I hope people do not blindly purchase for use without checking which plates or designs they have already on premises.
all brands nowadays find it easiest to up-sell by creating minor differences but major incompatibility ’cross various models/designs even from the same brand/company.
and lastly, all these on-line stocks or on-line only lots may not always have as rigorous quality checks or defect tolerance as when bought in store/ physical channels. http://www.amazon.in/Havells-Oro-High-Speed-Reg...
