<p>The present invention relates to a sheet type switch unit and a mat comprising the same. It includes a pair of substrate sheets which have a printed circuit pattern which has contact switches which is divided into several groups on a soft and wide sheet, a switch unit which has an air hole which is located in each of the contact switches between the substrate sheets. A soft-square upper member is formed on the upper side of the switch unit. A buffer member which has higher hardness than the upper member is formed on the lower side of the switch unit. According to the configuration of the present invention, it can prevent damage and smoothly operate the switch unit, completely absorbs impact transmitted to the bottom. Also, it can be easily replaced with a wide mate as user′s need regardless of void size due to the limit of injection molding.</p> |
