# Touch and Push Buttons

The Hapticlabs DevKit includes two types of sensor boards designed to trigger haptic effects.

# Touch button (Capacitive touch sensor)

The Touch button (Capacitive touch sensor) allows triggering tracks with a simple touch. It consists of a sensing area, where contact is detected, a JST PH-4 4-pole connector and two 2.5 mm mounting holes for connecting it to your Prototype.
To the left of the connector, you'll find two small switches to select which GPIO pin will be triggered. To choose the track assigned to PIN 1, toggle switch 1 to ON. For PIN 2, toggle switch 2 to ON.

# Push button (Dual button sensor)

The Push button (Dual button sensor) allows triggering tracks with a simple button press. It consists of two buttons, a JST PH-4 connector and two 2.5 mm mounting holes. Button 1 triggers the track saved to Pin 1, button 2 triggers the track saved to Pin 2.

Tip: Upload two different tracks to slot 1 and 2, and compare them in A/B tests!
