The invention relates to a card type power access device used by a hotel. The power access device comprises a card electricity taking identification circuit and delay circuit, a voltage comparison circuit, a photoelectric coupling zero crossing silicon controlled rectifier driver and 220 V commercial electric power switching circuit, and a 9 V direct current regulated power supply. According to the invention, on the basis of reservation of a power saving design concept of an existing card type power access switch, a core device of the card type power access device used by a hotel employs a photoelectric coupling zero crossing silicon controlled rectifier driver and bidirectional silicon controlled rectifier noncontact switching; and defects that a contact of a traditional electromagnetic relay is easy to be ablated and be damaged due to sparking are overcome; therefore, an objective of noncontact large-power switching of 220 V commercial power is achieved. Moreover, the installation and utilization of the card type power access device used by a hotel enable a power-saving effect to be good and a fire potential in a standard room to be effectively eliminated.
