I was wondering what the ratings on a DPDT switch mean? and how to read them properly?
I have some DPDT swtiches. On one side is says ON OFF (the function of the switch) and on the other is says 3A 250V AC (and) 5A 125V AC. I was just wondering what this actually means? I want to use the switch in my car, which has ~12-14V DC, so what would the amperage be for the switch in this case?
Thanks in advance..
1.DPDT (Double Pole Double Trough)
2. For 250 VAC can handle max.3 Ampere.
3. For 125 VAC can handle max.5 Ampere.
4.If you use for 12 ~ 14 V DC, it's OK, load 5 Amp ( 60watt), by parallel the DPDT become SPDT (Single Pole Double Trough).
The switch only for +, usually - (neg) direct to the load.
But I suggest (usually I do), use this switch combine with Relay 12V.
So the switch load is only for the relay (very small Amp, very long life), than from relay to the Load.
Find the relay on Car Accessory Shop, If use for 100 Watt Lamp, look for 10 Amp Relay or more.
200 Watt, 20 Amp Relay or more. etc.
There's drawing on the Relay. how to connect. Dont' forget to fix a fuse.
Clear?
