| 摘要 |
A safety double-break switch (100) is disclosed to include a housing (10), which has a button (14) pivoted to the main body (11) thereof, and a first circuit breaking mechanism (20) and a second circuit breaking mechanism (30) respectively mounted in first and second accommodation chambers (112, 113) in the housing (10) and respectively connected to external power source. When biasing the button (14) to ON position, the first circuit breaking mechanism (20) and the second circuit breaking mechanism (30) are electrically connected with the power source, thereby resulting in the current flow. When biasing the button (14) to OFF position, the first circuit breaking mechanism (20) interrupts the power source to form a first broken circuit, and the second circuit breaking mechanism (30) interrupts the power source to form a second broken circuit.
