I'm trying to wire up a Schurter CPS16 capacitive, multicolour (RGB), anti-vandal switch to my PC for use as a power button.

The switch function is momentary and normally-open.

Schurter CPS16 Capactive Switch

Tech Sheet

I'm just not sure what needs wiring up, and to where:

  • I can get 5v or 12v (and Ground too, I suppose) from a Sata Power connector
  • Obviously I need to connect the motherboard power button pins
  • I have a free RGB header (and an RGBW currently in use)

I'm keen to learn what's involved! Any assistance is appreciated :)

  • \$\begingroup\$ @jsotola I don't have another think, but its direct from a reputable manufacturer's site? \$\endgroup\$ – Paul Shaw Jan 16 '18 at 2:44

Some reading of downloaded materials is necessary as well as awareness of the PC PWR_enable Low from normally open momentary switch contact points between input and gnd.

Pins 2,4,8 will be all gnd on a PC since they use "active low" enable toggle ON OFF. Normally activated on release of the switch.
