摘要
<p>The control apparatus (100) has touch-sensitive input surface (F) comprising predetermined component made of porcelain (P) such as Meissen porcelain (RTM: First European hard-paste porcelain). The ridges (E) are formed in the touch-sensitive input surface. The touch-sensitive input surface partially consists of a glass layer to which the porcelain is adjacent.</p>
