Abstract
The invention relates to a method and an apparatus with circuitry comprising at least one mechanical switch serving to open and/or close an electric contact and a processor unit serving to perform first query and a second query of a contact state of the contact, with the processor unit further serving to provide an output signal on the basis of information on a change of the contact state of the contact detected by means of the first and second queries, wherein the processor unit is configured to perform the second query after the first query with a timing so that the second query precedes an expected bounce of the contact.
