24V capacitive touch switch

[erpi]

Hi all,

I'm planning on making my own home automatisation system using a siemens PLC and interfacing it with Domoticz using Node Red & MQTT.

The problem with a Siemens PLC is that everything needs to happen at 24VDC.
I'm currently unable to find a good capacitive touch switch that works on 24VDC.

Do mind that design is also important.

Does anyone have any suggestions?

Thanks!
