STECS/STEM TGL UP/DN switch stopped working

[hoot]

Hello,

it seems the switch has just got broken: neither UP or DN results in any action. The switch actions are also not recognized in VKB Device Cofig > Test.
How can it be replaced/fixed?

Thanks in advance.

Best regards
hoot

Actually I bought it here, directly in your online store. I will place the ticket by the order.

Edit: resolved. Thank you.
