[0024] The utility model is further described below in conjunction with the accompanying drawings: As shown in the figure, a leakage protection switch with an anti-deformation installation structure includes a base 1, a boss 11 is provided on the base, a leakage protection mechanism and an action mechanism are installed in the boss, a detachable back cover 12 is provided on the boss, and a buckle 21 is provided on the circumferential wall of the boss, a buckle plate 22 is provided on the back cover and is engaged with the buckle; a reinforcing plate 23 is arranged opposite to the buckle at least one place, and the reinforcing plate extends along the height direction of the boss. The action mechanism and the leakage protection module (which can be a circuit board and a mutual inductor) can refer to the Chinese patents CN215988630U and CN216749753 U. The mounting plate can be arranged relative to the buckle, specifically, it can be arranged at a distance of 1~5cm, which can effectively prevent deformation.

[0025] In this embodiment, as shown in the figure, the buckle plate is provided with a buckle groove 221, the buckle is arranged in the buckle groove, and the inner wall of the buckle groove is limitedly matched with the circumferential outer wall of the buckle. The buckle is completely arranged in the buckle groove, and is limitedly matched with the three inner walls of the buckle groove, and only the upper opening is used for loading, and the limit is better.
