Abstract:

An opening switch and a remote circuit breaker. The opening switch comprises a base and an energy storage assembly (100) and a lock latch member (200) which are provided in the base; the energy storage assembly (100) is provided on an inner wall of the base; one end of the lock latch member (200) is hinged with the base; a lock latch protrusion (210) is provided on the lock latch member (200) and comprises a barrier wall (211); the barrier wall (211) is used for when abutting against an energy storage arm (140) of the energy storage assembly (100), enabling the lock latch member (200) to have a tendency to rotate under the action of the energy storage arm (140), so as to keep the energy storage assembly (100) in an energy storage state. Therefore, the lock latch protrusion is facilitated to abut against the energy storage arm of the energy storage assembly, so that limiting between the energy storage assembly and the lock latch member is enhanced, and the stability and anti-interference capability of the whole remote circuit breaker are improved.
