Hello Everyone,

I am looking to use a Round shaped switch (SPST or DPDT or SPDT) rated >= 48V DC, 4A (max). But, I could not find round, illuminated and latched switches for this voltage and current rating.

I found some switches from "Wurth Electronik" with manufacturer part number 471002268142. But it is rated at 28V DC, 10A. Can I use this switch for 48VDC, 3.5A application?

I am relatively very new to electronics. Please excuse me for silly questions/terminology.

Thanks a lot in Advance.

Regards,
Keerthi

Welcome to AAC!
Could you use a round illuminated switch to operate a relay instead? I'm sure you'll find it easier to source those.

There's a reason why manufacturers specify parameters and unless you think you know more then them, you're supposed to follow their recommendations.

Depending on your application, you can use the switch to control a MOSFET, solid state relay, or mechanical relay.

Thank you for the reply. I am looking for a panel mount switch which should be operated manually. I would be looking for a better switch then.

There are many industrial sources of panel mount switches from such as Group Shneider, Idec and many others, in some instances you can make up the switch functions as add ons to stack or select N.O. - N.C. etc.
You can obtain these in different colours, some with illuminated lenses and opaque fronts where legends can be custom made at will very easily.
If you want quality, look at the Industrial selection also probabally available at you local electrical suppliers.
Max.
