Is the following pin-out correct in the schematic? Aren't 1 & 2 supposed to be switched with 3 & 4 (on other side of open latch drawing)? How would I wire this diagram so that I am only using 2 pins?
Its just supposed to be a simple on-off switch. This is from the documentation/models provided:



Isn't this the correct way:
I've tried to achieve that orientation with Rotate and mirror change but with no luck.

 

Is the following pin-out correct in the schematic?

How are we to know without having the switch, datasheet, or intended application?

Both orientations of the switch are functionally the same.

You didn't provide info on the switch, but the diagram makes it look like you could use terminals 1&4, 1&3, 2&4, and 2&3 because terminals 1&2 and 3&4 are connected internally.

 

According to the B3F-4055 data sheet that is a simple P.C. PB switch with 1&2 switched to 3&4 with the P.B. action?

 

The two diagrams are effectively the same.
The thing to note is that the pin spacings are not the same in both X and Y directions. The pins lie on a rectangular grid and not a square grid. You have to double check which pins are connected.

On the switches that I have the spacing between the switch contacts 1&4 or 2&3 is 4.5mm.
The spacing between 1&2 (also 3&4) is 6.5mm.

You only need to connect to two pins since 1 is already connected to 2.
Pins 3 and 4 are already connected.

Ok got it. So I can leave 2 of the not-connected PINS unattached to anything if I want.

I will supply them next time.

 

Yes, used principally to secure the switch to the P.C. board.
Data sheet is on the Digikey site.

 

Here is an example of a switch from CUIDEVICES.

I'm going to connect PS wire to lead 1 and when switch button is pressed it will continue through lead 3. In the EasyEDA program do I do something with those unused leads 2 & 4? I don't need them.

I really like this one: Awesome Button
Or add to existing tactile: Tactile Caps

Like I already mentioned, they are there mainly for mechanical support, they do not offer any extra electrical benefit.
They are only 50ma 24vdc resistive rated.

NP thx. I was just hoping the EDA program would see it your way.

 

Do recognize this is a momentary contact pushbutton. Only on when you're pressing it.

 

Uggh thank you! Back to the drawing board: what search term would I use to indicate non-momentary switches? Do non-momentary switches have a special term?

Also I've uploaded a photo of the circuit schematic. If we can pretend that the switch is not momentary can I add a standby switch to the circuit? Standby would indicate the circuit is off.

The current power switch is circled to identify it since its difficult to see.

 

For alternative , Look at a min slide switch Digikey 360-3680-ND Manuf No SMVA001

 

Latching pushbutton switches are not common in tactile switches.
Here is this I found. The force required to activate the switch would be much higher that "tactile" pushbuttons.

Push on push off.

 

Tactile switches are generally the wrong choice for a power switch.

The options are numerous:
□ toggle switch
□ rocker switch
□ slide switch
□ push-on/push-off pushbutton switch

The advantage of the first three types is that you can visually tell if they are on or off.

 

The one I quoted has the advantage.

So this looks great but I am using 15v
Electrical Capacity (Resistive Load) Maximum Level: 500mA @ 12V DC
Am drawing 168mv at 15V
All the "Pretty" ones seem to be at 12V. UUgh.
