1. An opening switch comprising:
a base;
an energy storage assembly; and
a lock catch assembly disposed on the base;
wherein one end of the lock catch assembly is hinged to the base, a lock catch protrusion is disposed on the lock catch assembly, and the lock catch protrusion comprises a barrier wall;
wherein based on the barrier wall being configured to abut against an energy storage arm of the energy storage assembly, under an action force of the energy storage arm, the lock catch assembly has a rotation tendency, so that the energy storage assembly maintains an energy storage state,
wherein the lock catch protrusion further comprises a transition wall, wherein the transition wall and the barrier wall are located on a same side of the lock catch protrusion, and
upon abutting against the energy storage arm of the energy storage assembly, the transition wall is configured to provide the rotation tendency to enable the lock catch assembly to be away from the energy storage arm.
