| 摘要 |
A switch detection system (100) includes a first switch (102) having a pole node (153), a normally closed contact (160), and a normally open contact (161), the pole node (153) of the first switch (102) connected to a voltage source node (104), a second switch (102) having a pole node (153), a normally closed contact (160) and a normally open contact (161), the pole node (153) of the second switch (102) connected to the normally closed contact (160) of the first switch (102), a voltage detector (106) connected to the normally closed contact (160) of the second switch (102), a first resistor (108) connected to the normally open contact (161) of the first switch (102), and a second resistor (108) connected to the normally open contact (161) of the first switch (102) and the normally open contact (161) of the second switch (102).
