I need to replace a switch on my older grinder. How do I know the correct replacement toggle switch to get? Some info on the current switch: CSA: 20A/12A, RU 19/12A, 125/250 VAC - do I need to find something that matches this exactly, or can I use something similar? The "RU" above may not be correct, but that's what the symbol looks like to me.
I am no expert on this but here is my take on the nomenclature. 20A/12A and 125/250 VAC are the two sets of numbers that I would look at first. 20A is 20 amps but it also is associated with the 125. While 12A is associated with the 250. What this means is the switch can handle up to 20 Amps while operated at 125 Volts, AC. It also means that it can only handle 12 Amps when operating at 250 Volts, AC. The next issue to look at is the size. Will it fit in the opening where your old switch went? Check all the specifications before actually purchasing the switch. I hope this was a least a little helpful.
