ABSTRACT:
An intelligent switching on/off socket includes a housing containing master jacks and slave jacks respectively containing master conducting strips and slave conducting strips, and a control circuit. The control circuit includes a current sampling circuit connected to the master conducting strips and a signal amplification circuit. The signal amplification circuit amplifies the sampled current and passes the signal to both a signal comparator, and to a reference signal acquisition circuit which in turn passes the reference signal to a memorizer. The signal comparator compares the reference current signals and current amplification signals, and is connected to a control output circuit. The control output circuit is connected to a relay which is connected to the slave conducting strip. The reference signal acquisition circuit provides a learning function such that multiple electrical devices with differing power needs can be switched on or off respectively depending on their individual power needs.
