PURPOSE: A cam-type switching unit is provided to reduce operation errors by being operated mechanically. CONSTITUTION: A first shaft is driven by an operating body and decelerates when the operating body is overloaded. A driving cam (20) is connected to the first shaft and has a guide part. A second shaft (30) is operated when the first shaft decelerates. A supporting device (40) opens and closes a switch when the first shaft drives normally. |
