Schema button ERC issue

[renegadeandy]

Hi all,

I added this switch to my schema(https://www.ckswitches.com/media/2567/pts647.pdf), using the footprint downloaded from mouser:https://www.mouser.co.uk/ProductDetail/CK/PTS647SM38SMTR2LFS?qs=sGAEpiMZZMsgGjVA3toVBHesIOE8acDv0HniJz6Wb%2Bs=

The switch has 4 pins, which I have connected up as I require.

When I perform an ERC, I get the following message:

For this given use of the switch:

Which to me is saying, that it doesn’t like the output of U1, which is 3v, being connected to pin 4, and that is then connected to pin 2 which is ground?

What is wrong with that? Have I made a mistake here?

For a switch, you should really define the pins as passive.

Ok - so alter the symbol to fix this? This symbol was downloaded from the mouser website, so I can only alter (didn’t originally make it!)

• Electrical type of schematic symbol pins (KiCad 4 and KiCad 5)

Bidirectional is meant for pins that can be either push pull outputs or input depending on system state. Connecting a push pull output to a power line would create a short. This is why kicad compains here. (In other words the mouser symbol is simply wrong.)

[bobc]

Yes, I would modify the symbol or make a new one.

Mouser library data is provided by Samacsys, I guess their data conversion is not optimised for Kicad.

All done, and it’s fantastic - works like a charm.

Thank you.
