Hi, for one Arduino construction I need one button which after pressing closes two different circuits . It should have 4 pins, but it is important that those 2 different circuits should not be connected after pressing the button.
So what I am looking for is basicaly two micro-buttons built in one.
It should be 90 degree micro push button, and it should look like this: NetDirect Demo E-shop
If you know what I am looking for, let me know.
Thanks in advance
What you want is typically called double pole, single throw (DPST). You might want to search for that, and add breadboard (or through hole) to your search. I did a google search and often times it finds single pole, double throw (SPDT). If you search for double pole, double throw (DPDP), there are more hits.
Here is the wikipedia article on switches to show the naming and wiring: Switch - Wikipedia
I think it is extremely unlikely you will find a DPST push-button in anything near that form factor, particularly right angle mounting.
Direct mounting, a bit bigger and with a solid plastic actuator, possibly.
DPDT switches are a lot more common, but they'll tend to be bigger as well.
Why do you need two separate throws on the switch? Is it because you need to send two different voltages? Or because you are making each throw one of the sides of an "AND" operation where one throw may have a voltage on it and the other not? If it is the first, you can control two transistor switches to switch in the necessary voltages and if it is the second and everything is logic-level you could simply use an AND logic chip like 74HC08 (these are about 25 cents each).
I think the best you will find is this
3 position with 2 set of contacts.
Wire one side with Common and Normally Open, and the other side with it's Common and NO.
When moved Up or Down, the Common/NO on that side will be connected.

Ah! That's the engineering question that people like us always think of, and tend to answer accordingly.
Tell us what you need, not what you think you need! Tell us the whole story.
