I Need a normally closed relay (can be normally open if it has to be I guess) that can be switched by less then 1mA @ 11 volts (1.25mA 11.35v to be precise) and handle a load of 8mA @11v (7.5mA 11.35v to be precise).
I'm pretty sure what I need is a solid state relay, but I can't seem to find anything. A Google search yields a few things but nothing concrete. Looking here https://www.vishay.com/solid-state-relays/ I found a few things that might work, but I don't understand half the specs on the data sheets. I've used regular relays for various things in the past but these go a bit over my head.
Basically I'm trying to fool a 3 position magnetic induction sensor into thinking that position 3 is switched at the same time as position 2. Position 2 sends a constant 1.25mA @11v until it's switched (and turns off) and I want to use this to switch a relay which will provide the position 3 wire with the 8mA @11v as soon as position 2 is switched.
My other concern is do SSRs have to have their current controlled (As in probably can't just give it any power source and ground it without burning out?)
There's a whole host of SSRs at that link that can be activated by 1mA or less... I just don't understand the rest of the specifications which is what I am asking about.

Seriously though I think you guys are assuming me to be more knowledgeable then I am. I really don't know half of what your saying or 80% of whats on the data sheets of the things you guys are suggesting (or how to use them).

Based on your supplied data sheet. If you look at attached image. 1ma is a butt hair away from not working. Your first goal should be to find a way to increase your current drive with something like a buffer or such.
Don't think I would have as much trouble if it was. I'm not an electrical engineer or going to school to be one. That's my small problem .
I hate to ask but can someone just tell me what electronics piece I need and how to wire it based on what I said in the first post. The diagrams and stuff don't really help me because I don't know what they say. My electronics knowledge is very basic. Don't get me wrong though I've looked up all the data sheets of the pieces you guys suggested, and tried to research what I need to do but cant really understand it.
