List of electrical switch types?
« on: September 14, 2018, 10:45:13 pm »
Does anyone know of a list of electrical switch types eg transistors, relay, reed

I can't seem to eliminate hand/manual switches & buttons from my results.

Thyristor, Triac, Solid state relay, analog switch,

Why do you want to eliminate manual buttons? Is it to automate a machine which was previously manually controlled with buttons?

For low level signals, analogue switches can be used, but the come with a set of restrictions such as the signal level being switch normally has to range within the analogue switch IC's power rails.

It's for a switching circuit.
I'm trying to make it as simple as possible.
Have two low voltage batteries, when one drains dead I want the low voltage to trigger the switch - which connects up the fresh battery. It's just for a torch, so delay between switching is okay.

What voltage batteries and what exact circuit/components are you switching (i.e. voltage/current/load)? This makes a difference with the best advice. Till then some ideas can be found by searching in google or google images for "low battery backup circuit" or something like that.

Just in case your an absolute beginner are you aware you can wire the batteries in parallel for increased current? If this is no advantage in doing so you might want to also mention what exactly your doing.

Here is my original post.
I'm very flexible around the voltages, nothing set in stone yet. Going for low voltage DC, even prepared to make my own custom battery packs if need be (to get a specific low voltage to avoid resistors).

Thanks for info, I'll check that out.

As people already responded in your other thread, you have given no reason why you would want to switch from one battery to another. Nor have you explained what problem you are trying to solve and what your ultimate goal is. This makes it very difficult for you to obtain the right answer. As it stands people can give you lots of answers, but most likely they will all the be the wrong answers due to lack of information about the problem.

Recommendation:

Explain what it is you are trying to do, without trying to propose any kind of solution in your explanation. Don't mention switches, resistors or anything like that.

Ask people to suggest to you the best solution to your problem.
