工作原理：
一进一出：常闭式：当线圈通电时，2通向1，1与3关闭。当线圈断电时，2与1关闭，1通向3。
常开式：当线圈通电时，3与1关闭，1通向2。当线圈断电时，3通向1，1与2关闭。
一进二出：当线圈通电时，1通向2，1与3关闭。当线圈断电时，1与2关闭，1通向3。
二进一出：当线圈通电时，2通向1，3与1关闭。当线圈断电时，2与1关闭，3通向1
How it works:
Entering and exiting: Normally closed: When the coil is energized, the two leads 1,1 and 3 closed. When the coil power, the 2 and 1 off, 1 leads to 3.
Always open: When the coil is energized, 3 and 1 off, 1 leading to 2. When the coil power, the 3 leading to 1,1 and 2 closed.
One into two: When the coil is energized, 1 leading to 2,1 and 3 closed. When the coil power, the 1 and 2 closed, 1 leads to 3.
Binary one: When the coil is energized, the two leading to 1,3 and 1 closed. When the coil power, the 2 and 1 off, 3 leading to a
