Automatic change-over switch apparatus with anticreep sampling wires

The utility model provides an automatic change-over switch apparatus with anticreep sampling wires, which comprises a circuit breaker, sampling wires and a power supply sampling device. The circuit breaker comprises a plurality of circuit breaker hand baskets. The power supply sampling device comprises a plurality of terminal plates and a fixed plate. The terminal plates are fixedly connected with the fixed plate. The fixed plate is fixedly connected with the circuit breaker. The fixed plate is provided with wire passing holes positioned corresponding to the circuit breaker hand baskets. Each terminal plate is electrically connected with one sampling wire and is placed deeply inside one circuit breaker hand basket respectively. By means of the apparatus, the condition that sampling wires drop out to be disconnected with the cables of users during usage can be effectively avoided. Meanwhile, the installation speed is accelerated, and the probability of failures is reduced. The working efficiency is improved.
