ABSTRACT:
The present invention relates to a power supply terminal of connecting devices of electrical conduction that includes an insulating terminal block. An earth wire connecting block, zero wire connecting block and two live wire connecting blocks are juxtaposed in said terminal block. Said earth wire connecting block, zero wire connecting block and two live wire connecting blocks respectively have the corresponding wiring input terminal and wiring output terminal. It is characterized in that said terminal block also includes a switch module with wiring input terminal and wiring output terminal, corresponding connections and conductions between said wiring input terminal, said wiring output terminal and said live wire connecting blocks can be carried out through the connectors; switch module is arranged between two live wire connecting blocks and is adjacent to two live wire connecting blocks; switch module includes a input sub-connecting block and two output sub-connecting blocks, wherein said input sub-connecting block set up wiring input terminal and switch end; said output sub-connecting blocks respectively set up wiring output terminal and switch end; said two live wire connecting blocks respectively set up switch end; said connector is connected between said switch end. The present invention has strong adaptability.
