La description
Round Domes are circle shaped switch contacts that were designed
for mounting on membrane circuitry . The domes are placed on a
membrane switch by means of pressure sensitive adhesive tape . When
they are pushed , the centers of the domes collapse past the flat
plane and make contact with the secondary pathway , thereby closing
the circuit .Â
