I’ve got a switch off a tile saw that stopped working and I can’t find it anywhere. Can you guys tell me which numbers matter the most. I mean I know what ip54 is and what amps and vac mean but why are there parenthesis around certain numbers and such? What do all these numbers mean? This is a 4 prong rocker switch as you can tell by the pics.

Hello,

The IP-code is a measure for solid particle protection and liquid ingress protection:
https://en.wikipedia.org/wiki/IP_Code

The VAC is the maximum allowed AC voltage.
The VDC is the maximum allowed DC voltage.
Also the maximum allowed current is given for VAC and VDC.

Ok but why is (10a) and (16a) in parenthesis and 12 and 18 aren’t? Is 18 and 12 the maximum? And 10 and 16 what it normally runs at? Also why does it say 20A on the bottom? I’m not a electronics guy but just want to know. I like to understand stuff
