Among them, HD should stand for HEAVY DUTY, but I’m not sure what SQ and RD mean; I’d appreciate everyone’s help.

In the petrochemical industry, the abbreviation SQ stands for super-fast ； square ； Square Noise Suppression http://treasure.1x1y.com.cn/useracticles/20061222/20061219113313023.html RD: Circle ； For the round button, http://www.zftrans.com/favorite/vocabulary/2009-1/22/1247091221247182043486.htm – the corresponding translation seems to be square heavy-duty rotor and cylindrical heavy-duty rotor
