The invention relates to the field of rail transit signal equipment, in particular to a safety switch (100) and a switch machine with the same. The safety switch (100) comprises a rack (2), a driving plate (3) and at least one travel switch (4). The function of the safety switch (100) is realized depending on the swinging of the driving plate (3) relative to the rack (2) and the mutual cooperation among the driving plate (3), the travel switch (4) and the baffle plate (13), and when the driving plate (3) swings to a cut-off position under the operation of external force, the driving plate (3) can just touch the travel switch (4) arranged on the rack (2) and disconnect the contact of the travel switch (4) so as to cut off the power of a motor (11) of the switch machine. And driving the baffle plate (13) to move away from the crank operating end of the speed reducer (12), so that the switch machine can be operated by a crank outside the switch machine. Therefore, the maintenance operation of the switch machine is more convenient.

    本发明涉及轨道交通信号设备领域,特别是安全开关(100)及具有其的转辙机。该安全开关(100)包括机架(2)、驱动板(3)、至少一个行程开关(4)。安全开关(100)的功能实现依赖于驱动板(3)相对于机架(2)的摆动以及驱动板(3)与行程开关(4)及挡板(13)之间的相互配合,当驱动板(3)在外力操作下摆动至切断位置时,驱动板(3)刚好能够触动设置在机架(2)上的行程开关(4)并使其触点断开以将转辙机的电机(11)断电,以及驱动挡板(13)从减速器(12)的摇把操作端移开,以使得在转辙机外部可用摇把来操作转辙机。如此,使得转辙机的检修操作更方便。
