I am looking for a way to switch 10 contacts but without having to switch these tiny contacts one after another. So basically one movement, 10 contacts open/close. I saw this little switch: switch

But there I have to swtich them all. Unfortunately I didn't find anything useful in the Internet.

The LEDs on the schematic are there to check if the connections are good from connector to sockert and back. I want to check each socket(10) with this 10 LEDs. Is this possible with a Multiplexer (can you put current throught a Multiplexer?)


I am grateful for any kind of help. King regards

  • \$\begingroup\$ @SunnyskyguyEE75 Thanks for your answer. Vnom = 5V, Current per contact = 30 mA. \$\endgroup\$ – pfra Jul 6 '19 at 14:48

    \$\begingroup\$ 10 x 10? So, 100 contacts? I think it may be time to re-think your solution by explaining what exactly you are trying to do in your question. So go make your question better! It may be that the better solution has nothing to do with switches. \$\endgroup\$ – st2000 Jul 6 '19 at 15:46

There are many solutions. When you define cost and user interface, the choices get smaller...and smaller. When they go to 0, you change your specs'.

There are binary analog MUX and mechanical rotary MUX switches if you search harder.

Try here or here.

You might even consider a pot' controlled current with a transistor. But learn to start with a functional and interface spec'. Better specs' mean a better design with more choices.
