An electric current is a flow of charged particles, such as electrons or ions, moving through an electrical conductor or space. It is defined as the net rate of flow of electric charge through a surface.[1]: 2 [2]: 622  The moving particles are called charge carriers, which may be one of several...

Digital Code Rotary Switches is similar to the regular rotary switch, except the outputs are binary encoded to save on pin requirements. 波段开关，是一个很古老的名字。实际上应该叫做多刀多掷开关，因为它不仅仅能做波段开关，也能做其它的用途。

Limit switch is a switch operated by the motion of a machine part or the presence of an object. A limit switch can be used for controlling machinery as part of a control system, as a safety interlock, or as a counter enumerating objects passing a point.[1] Limit switches are used in a variety of...
