They make mechanical "push-on/push-off" push-button switches, like: https://www.radioshack.com/product/index.jsp?productId=2049717

You can connect the switch to the clock input of a flip-flop, such as a CD4013, with the D input connected to the /Q output. This will toggle the FF for each push of the button.
You would need to add a debounce circuit to the switch output to avoid multiple toggles.
I know what you mean, and it's puzzling. Perhaps the OP got his answer so didn't think he needed to reply. But it's just common courtesy to acknowledge any help you've received. Maybe it's a cultural thing.Cruts, I've read a few of the OP post's and started threads. Usually our forum members respond with a couple suggestions, then nothing from the OP?
Edit: I could be wrong, just seems like a lot of their threads end up that way.
Do you have a debounce circuit design and parts for that?I want to run about 8. So 4 IC's will do the trick. Time to get to ordering some
Thanks for the help
That would work also. If you use a 556 you will get two 555's in one package, reducing the chip count by 1/2.The Flip/Flops will need switch debouncing.
There is a page showing several interesting toggle circuits here

The 555 timer has an internal flop and would be my choice.
Nice circuit Mike.Here is a sim of the circuit the KV linked. It seems to do the right thing with respect to switch bounce. The rc network defines a window during which further pulses from a bouncing switch are ignored.
I posted it in 2007.I found this schematic in a dead thread.
Hey guys, using a momentary button switch, I want to toggle an on off signal.
Whats the best way to accomplish this?
Is there an IC available that can do this?
Or do i have to do it manually and get a bunch of NAND gates and hook them up?
I haven't drawn the debounce circuit yet. I just got the CD4013 IC's today.
I'll get onto thata bit later perhps.
Its for both, logic and operate relays. I have a 5V power supply for it, some of the switches will go to an arduino, others will go to a transistor, then to a relay to for example, switch on car park lights, among other things
