Rotational Push Switch

A rotational push switch, comprising:

• a bottom shell, comprising a first conductive terminal, a second conductive terminal, and a third conductive terminal mounted inside the bottom shell;
• wherein one end of the first conductive terminal and one end of the second conductive terminal respectively extend outward from a front side of the bottom shell;
• wherein one end of the third conductive terminal extends outward from a back side of the bottom shell;
• a conductive elastic piece;
• wherein one end of the conductive elastic piece is mounted inside the bottom shell, and is electrically connected to the third conductive terminal;
• Wherein another end of the conductive elastic piece elastically contacts the second conductive terminal;
• a top shell, correspondingly engaging with the bottom shell;
• wherein the top shell comprises an annular seat mounted on a top of the top shell;
• a switch assembly, mounted in the annular seat of the top shell to press the conductive elastic piece to make the conductive elastic piece and the second conductive terminal electrically connected or electrically isolated;
• wherein the switch assembly comprises a rotatable push unit, and the push unit comprises a plurality of alternately arranged ON symbols and OFF symbols mounted on a top of the push unit;
• a cap, slidably mounted on the top shell to correspondingly press the switch assembly to make the switch assembly press the conductive elastic piece;
• wherein the cap comprises a display window mounted on a top of the cap;
• wherein when the conductive elastic piece is electrically connected to the second conductive terminal, the display window aligns with one of the ON symbols of the push unit;
• wherein when the conductive elastic piece is electrically isolated from the second conductive terminal, the display window aligns with one of the OFF symbols of the push unit.
