Abstract
A contact switch, contact switch system, and interactive building block system carrying the contact switch based on UHF RFID technology for detecting mutual contact events are provided. The contact switch system includes a plurality of contact switches each including a chip and an antenna not connected to the chip. When the contact switch is in contact with another contact switch, the chip is connected to another antenna of the another contact switch and the antenna is connected to another chip of the another contact switch. The chip receives and converts a radio wave from the another antenna into power, and the power converts identifying information of the chip into a radio wave, which is sent to a reader. When the reader reads two encoded identifying information at the same time, whether the two contact switches are in contact with each other is determined by the contact switch system.
