ABSTRACT:
This invention relates to a namecard holder and in particular to one including an electrical circuit and a control switch disposed at one side of a notch of an open end thereof. The control switch has a conducting plate and a curved spring leaf which are normally in contact with each other. The spring leaf is provided with a lower end for preventing namecards from leaving the holder unintentionally. When a namecard is partially drawn out of the holder, the conducting plate will be separated from the spring leaf thereby activating the electrical circuit and as the namecard is completely drawn out of the holder, the conducting plate will contact the spring leaf again consequently actuating a musical or speech IC and a pressure electrical vocal producer to send out music or speech to appeal the visitor's attention.
