A button pusher (Ukrainian: кнопкодав, Knopkodav) is a term in Ukrainian politics and society related to a member of the Verkhovna Rada of Ukraine (the parliament of Ukraine) who votes on a motion by using their own identity card as well as ones belonging to other deputies. This voting is done either with or without the consent of the absent deputies. On 2 March 2021 sensor technologies were installed in the Ukrainian parliament that were designed to make it impossible for MP's to vote on behalf of absent colleagues (since they need now to use both their hands for a single vote).
