摘要： A sensor switch includes a ceramic body, first and second conductive units and a conductive member. The ceramic body includes intermediate, bottom and top layer assemblies cooperatively defining a chamber. The intermediate layer assembly has an intermediate layer inner peripheral surface. The first conductive unit has a first conductive layer covering the intermediate layer inner peripheral surface. The second conductive unit has a second conductive layer protruding from the bottom layer top surface and spaced apart from the first conductive layer. The conductive member is rollably disposed in the chamber and is limited by the second conductive layer for forming a current path with the first and second conductive layers.

摘要： An embodiment modular light-emitting diode (LED) display panel includes attachment points for use in attachment as part of a multi-panel modular LED display, a printed circuit board including a first side and an opposite second side, and a plastic casing attached to the opposite second side of the printed circuit board. A perimeter of the plastic casing is substantially rectangular and has a height and a width. The modular LED display panel further includes a display surface including a plurality of LEDs arranged as pixels and attached to the first side of the printed circuit board. The pixels are arranged in a rectangular array including at least fifty pixels. Each of the pixels of the rectangular array is spaced from each respective adjacent pixel of the rectangular array by a pitch. The pitch is a predetermined constant number. The pitch does not depend on the height and the width.
