The buckle 201 may be disposed on an inner surface of the case peripheral wall 220, the clamping groove 101 may be disposed on an outer peripheral surface of the base 100, the case peripheral wall 220 and the base 100 are in limit fit in a width direction of the key cover 200, and the buckle 201 and the clamping groove 101 are in limit fit in a thickness direction of the key cover 200.

Therefore, the base 100 can be limited in two different directions, so that the connection stability between the key cover 200 and the base 100 is improved, and the base 100 can obtain a better fixing effect. Meanwhile, by adopting the arrangement, the fixing effect is improved, and meanwhile, no additional connecting piece is added, so that the material quantity and the material cost can be effectively controlled. Meanwhile, the arrangement of the buckle 201 and the clamping groove 101 can also prevent the button housing 200 from warping and the like in the thickness direction, and the structural fitness is improved.

Alternatively, the key body 400 may include a body portion 410 and a sealing ring portion 420, the sealing ring portion 420 being disposed around the body portion 410. The base 100 may be provided with a first receiving groove 102, the key circuit board 300 is received in the first receiving groove 102, and the mounting chamber 10 may include the first receiving groove 102.
