The utility model provides an automatic sequential switch, comprising a rotating shaft 12, and a plurality of insulating plates. A plurality of switch driving blocks are arranged on the rotating shaft 12; a plurality of switch contact points are uniformly distributed along the circumference direction on the insulating plate to control the rotation of the rotating shaft 12. The conduction and closure of the switch contact points are controlled by the switch driving blocks. The utility model has the advantages of simple structure, long service life, and less resistor contacting, which is particularly suitable for places of measuring various different signals in sequence with a measuring meter.
