Where can I get a "Non-Momentary" Lighted button switch? Answered

I'm working on a project which requires a lighted button switch. I need the light on the switch to turn on when the button is pressed and stay on after the button is released. Then I need it to turn back off when the button is pressed and released a second time. I bought a lighted button switch only to find out that it can only be constantly on or only on when the button is held down (or off depending on how you wire it). This will not do for my project. Does anyone know where I can get what I need or if there is a way to tinker with the switch I have and make it do what I want? 


Here are 7 places to look, all places from which I have ordered in the past.

DigiKey Select "Standard, Illuminated" and whatever else you want to narrow it down. I you click "Apply Filters" after each selection, you can see fromhow many you have to choose.
Jameco They have some, but probably not quite what you want. :(
MCM Electronics Same comment as Jameco.
Mouser Similar in use to the Digikey site.
All Electronics Same as Jameco and MCM, but you never know what they get in, so keep checking.
Electronics Goldmine Sort of a buyout/clearance center type of place - always getting new/different products in. Worth a try.
Parts Express Mainly geared toward audio building, but has parts available.

Do you really have to have the switch light up, or is an indicator adjacent to the switch an option? If so, an LED and the prerequisite dropping resistor is a heck of a lot cheaper than the additional cost of a lighted switch. BTW, you can drop the current on an LED quite low and still have similar illumination to full current, if battery power is used.


The button does need to light up. I'm using it as part of a Tony Stark plushie and the button is his arc reactor. The button is for no other purpose than to light up and look good. It's either this or I spend the money on materials for fabric pressure switches from LessEMF and casting supplies to cast the arc reactor out of resin, which is more expensive. I actually decided to go this route because it was cheaper. lol My only other idea was to install a switch inside the battery compartment, but I don't want to have to open the doll to turn it on.

Okay, we didn't know how it was going to be implemented. Of course, you could just put a pushbutton switch on the battery box to run the LED under the ARC Reactor. Probably less than the other ideas. Whatever way you decide to go, let us see what you end up with.

Good luck,

Okies. So I checked the sites and I think I found buttons that will work for me on Mouser. ^_^ Thanks all for the help, everyone! I'll post pics of the finished product when I get them!

We'll be waiting to see them! Glad you found something that'll work.


Your description is a bit confusing. First, the switch itself. Do you want it to be momentary-contact, or latched (stays on after pressing, until pressed again)? Whatever kind of switch you get, that is how the light will work.

Take a look at what McMaster-Carr offers. In the left sidebar, select "maintained" and "illuminated", and you can narrow down your choices from there.

As I said, I want a non-momentary lighted button switch. Thank you for the site you provided. Sadly, they charge more than I can afford to put into the button for this project. The button I have cost me less than $4. They want over $20. Since I'm making 6 of these, that would be too expensive to make it feasible to me.

Yes, McMaster-Crr is pricey for electronic stuff, because that's not their main business. However, it does give you the right keywords to use ("maintained contact", "latched contact") to search real electronics sites (DigiKey, Jameco, Mouser, RadioShack). A lighted push-button switch ought to cost you between $2 and $5.

Ah, okies. Yes, I will look into those sites. Thank you very much. ^_^

Ok. Here are some pics of what I have so you understand fully what I'm working with.

This is the switch box in the "off" position, with the cover removed:
Here it is in the "on" position:
Here it is with the cover back on and attached to my button assembly, "off" position:
And again, "on":

All I want is a way to make the switch stay down, in the "on" position, after the first press of the button and release (turn off) with the next press. It would be easier if I could just buy a button like this that has such a thing built in for a cheap price. If I can't do so, then I'll have to mod what I have. So, can anyone tell me a good way to do this?

As Dave says in the video i posted buttons are often the most expensive part of most electronic projects. So building your own soft latch power button is your best option to keep costs down. Sure it involves a bit more work but in the end you have a cheaper and better product.

The kind of switch you want is an illuminated push button that latches. They average about $15. You can find them for as low as $2 but they may be too big for your application.

You can by a basic latching switch and add an LED to it. When you push the button it locks into the down position and powers on your device lighting an LED you place right next to the switch. The LED then back lights the button cover you have for the switch. No need to try and build the light into the switch housing.

Here is an idea for you. Make your own.

What you'll need to do is create a soft latch power switch circuit. This is the same kind of circuit used in most electronics now so you have a single push button that turns the item on and off. When the device is powered on it can also light an LED. This you can place near the push button. Then create your own translucent button that can make contact with the push button and allow the LED to shine through it.

Here is a great video which outlines the circuit and how it works.
