Question Transistor Switch recommendations?

Decades ago I used to know all I needed to build an electronic gadget.
Now I have no clue what parts even exist.
However, I need to set up something that requires a switch. Input 5 V, max 2 mA. Output 14 V, more amps is better, but not important, I can use a relay to feed the load 3 A. Is there a transistor IC that can do it for me?

I would highly recommend the ELK 924 relay module to do what you need.

What you describe is a Solid State Relay. No mechanical contacts.
Here's a $12 example from Amazon.

I feel your pain Bitjam. We come from an age of emitter, base, and collector and like you, I no longer know what is available. The pros here are good (and a bit younger) so I always know where I can ask. Well at least some are younger (Furd).

Yes, I'm younger than some but is 67 years really considered young?

Oh, like Guy I also thought of a solid state switch.

I'm not a big fan of those solid state relays switching DC.
In this members application I'm sticking with the ELK board.
