# 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).

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.
