Abstract
A switching device includes operating members independently movably supported at opposite sides of a lid, a spring having a pair of rotary shaft parts disposed on the inner side of the lid so as to advance or retreat under the influence of the resilient pressure of the spring, and lock members disposed on opposite sides of an opening of a box body so as to detachably fasten the rotary shaft parts thereto. The rotary shaft parts are connected to the operating members so as to urge the operating members outwardly away from each other by virtue of the resilient pressure of the spring and are removed from the lock members by depressing motion the operating members. Owing to the construction, the lid is ensured to produce an infallible shut state on the box body by bringing the rotary shaft parts into engagement with the lock members due to the resilient pressure of the spring. The lid can also be infallibly opened in either of two directions by selectively removing the rotary shaft parts from the lock members by depressing either of the operating members.
