 About Key contact rubber strip For digital piano :



The key contact rubber strips are the media between the digital piano keys and the MK PCB board that makes the sound when press down the digital piano keys ,there's conductive carbon on each note of the rubber strip that conducts electricity . The carbon pad presses against a circuit board (the key contact board) and completes the electrical circuit when press down the keys .



How many pieces of key contact strip to order for your digital piano :



For example ,if the rubber strip you are ordering is 12 keys :



1.If your digital piano is 49 keys ,you should order 4pcs of 12 keys rubber strip and cut one rubber key from your old rubber strip to use together



2.If your digital piano is with 61 keys ,you should order 5pcs of 12 keys strip and cut one rubber key from your old rubber strip to use



3.if your digital piano is with 88 keys, you should order 7pcs of 12 keys rubber stip and cut four key strip from your old rubber strip ,or order 8pcs of 12 keys ,use 7X12 keys and cut a 4 keys trip from the last strip to use



If the rubber strip you are ordering is 13 keys ,same quantity as above you should order ,and no need to cut the last one key from old rubber but cut off 1 keys each from the first 3,4 or 7pcs of the strips and remains on the last strip .
