Abstract

The present invention provides a POS liquid crystal safety detection switch. The switch comprises: a touch screen, a touch screen connection line, a mainboard connection base and a POS machine mainboard; the touch screen is disposed on the POS machine mainboard; the touch screen includes a first edge and a second edge which are relatively arranged, the first edge is provided with a first port, thesecond edge is provided with a second port, and the first port and the second port are electrically connected to the mainboard connection base through the touch screen connection line; the touch screen is provided with a safety detection signal. When the touch screen is electrically connected to the mainboard connection base through the touch screen connection line, the safety detection signal isin an on state.

Description

technical field [0001] The invention relates to the field of switches, in particular to a POS liquid crystal safety detection switch applied to a POS machine. Background technique [0002] POS machine as a financial transaction terminal, its security is particularly important. Nowadays, more and more POS terminals use large-screen LCD display, because the device often contains many devices located under the liquid crystal. In order to prevent the liquid crystal from being lifted and obtain sensitive information of the device, the protection of the liquid crystal is very important. But now many POS terminals generally bond the touch screen to the surface of the liquid crystal, and then glue the whole body to the device's plastic case. The glue is prone to failure under heating, thus threatening the safety of the device. Contents of the invention [0003] The invention provides a POS liquid crystal security detection switch, and the device can effectively protect the inform...
