I am looking at this switch for use in a circuit: https://www.nidec-copal-electronics.com/e/catalog/switch/s-4000.pdf
The question that I have is in regards to the contact rating as follows:
Non Contact rating: DC50 V 100 mA
Contact rating: DC2.4 V 100 mA, DC24V, 10 mA


Am I correct to say that I would be ok to use this rotary dip in my 5v circuit using 5V and 5mA to the switch as my contact rating of DC2.4 V 100 mA, DC24V, 10 mA falls within these values?

For some reason this is confusing me and I want to be sure I am reading this correctly.

Thanks

Yes.
That's well within its ratings.

 

2.4x100 mA= 0.24 W Same for 24V x 10 mA. 5V x 5mA would be pushing it, but probably OK.

Edit: Math error. I must have seen 50 mA and got 250 mW, not the correct value of 25 mW.

 

Thank you all for your help with my question.

Why do you say probably?
25mW is well below the switches 240mW rating.

Sorry, bad math. I added a zero mindlessly. Corrected post.
