Tactile Switches Replacement
The tactile switches used in the SARK-110 are SMD components, which in case of failure they can be easily removed from the main board using a hot air gun. If this tool is not available, it will convenient breaking the contact pads using a cutter or a Dremel tool, being careful not to pull the pads off the board. Then desolder the leads and pads with an iron and clean them with the iron and desoldering braid. Finally put the connector in place and carefully solder the four contact pads using a thin-tipped iron.
