Abstract:
Disclosed are a disconnection safety lock and a dual power source switch. The disconnection safety lock comprises a sliding member (11), a first locking block (12), a first lock shaft (13), a first pressure spring (14) and a first lifting mechanism (15), wherein the first locking block (12) is fixedly connected to the sliding member (11); the first lock shaft (13) can be fastened to and locked with the first locking block (12); the first pressure spring (14) is used for making the first lock shaft (13) move along a direction toward the sliding member (11); and the first lifting mechanism (15) is used for making the first lock shaft (13) move along the direction away from the sliding member (11). The above-mentioned disconnection safety lock is capable of quickly locking the sliding member fixedly connected to a movable electrode at a disconnection position, ensuring the dual power source changeover switch is in a state of full disconnection.
