# Button

Quite straightforward - it's a button. It clicks.

The button is the **default way to control SimplePack devices** - downlink requests and activation/deactivation are done through the button. Our firmware can distinguish between various lengths of clicks (the time intervals can also be customized).

{% hint style="info" %}
Please note that the button functionality is rewired to the **Reed switch in SimpleIndustry and SimpleMeter devices**, but the behavior remains the same. All actions are just performed with a magnet switching the reed switch instead of a finger pressing the button.
