Clicky on/off switch

[Javid.zare.s]

Hi I'm creating a amp circuit and i need off on switch for it.
Im wondering if i can use this
Into the circuit board... (Normally they are ON as long as you hold them)

Hi,

With the use of a toggle flip flop or 1 bit counter.
You need a debouncing ciruit.

Thanks ,but as noob I didn't understand you...
Can you show me required circuit or components

If your circuit can supply about 5mA back using an SCR might be another way of doing it.
(switch SCR and probably a resistor )
The SCR will stay on as long as it gets the 5mA after pressing the button

Took me a while to find it but this is the sort of thing.

Your best friend can be a switch called "push-on/push-off" like :
---->
---->
Available in many sizes, and they do the 'clicky'.

Thanks , so as you said it wont use any power if its off.. Right? And 5ma when switch is on?

Javid.zare.s I think before going into the depths of switch types, you should tell us:
what the amp is,
what voltage are you switching and
what current are you switching.

Correct. It doesn't use any power when off - once on you need to keep the circuit drawing at least 5mA to keep it on.
(Hence the suggestion of using a LED - or just a resistor as explained in the link)
The 5mA figure is just the current require to keep the SCR conducting once it starts to do so.
If it falls below that the circuit switches off. (as in the link) Obviously if you use a different SCR from the examples the
5mA figure may change.

Well ,my amplifier is a tiny tda2822 with some resistores and capacitors which i managed to put into my headphone...
Battery is about 800mah @5 volts
I wanna add a off on switch and low current led ...

The simplest circuit I can find is the one using CD4093 on this page: http://www.technoblogy.com/show?VOO

It should easily switch the current you need but note the comment about using a power FET beneath the diagram.

Hi,

Look at MAX16054.

Its nice to see something simple and fun with so much creativity - that's a great link betwixt.
It's also good to see someone using breadboard neatly for a change.
