As shown in fig. 1 to 7, the present utility model discloses a switch including a base 100, a fork 200, a swing link 300, and a rocker 400. The base 100 is provided with a recess 110 having an opening at an upper portion, and the rocker 400 is hinged in the recess 110. The upper end of the swing rod 300 is hinged to the base 100, and the lower end of the swing rod 300 extends into the groove 110 to drive the rocker 400 to tilt. The outer side wall of the swing rod 300 close to the lower end is provided with a convex part 301. The convex portion 301 is arc-shaped. The lower end of the shifting fork 200 is provided with a jaw 201, and the jaw 201 is U-shaped. The upper end of the shifting fork 200 is hinged to the base 100, and the jaw 201 at the lower end of the shifting fork 200 is sleeved on the outer surface of the protruding portion 301. The swing rod 300 is linked with the shift fork 200, and the swing angle of the lower end of the swing rod 300 is larger than that of the lower end of the shift fork 200.

When the rotation angle of the shifting fork 200 is 2 degrees, the rotation angle of the swinging rod 300 is 4-6.5 degrees, namely the shifting fork 200 rotating at a small angle drives the swinging rod 300 to rotate at a large angle, so that the overall thickness of a product can be reduced. The utility model has simple structure, can realize ultrathin arrangement and form an ultrathin switch.

Further, the upper end of the shift fork 200 extends out of the driving arm 210 towards two sides of the swinging direction respectively, the upper end of the swing rod 300 extends out of the swing arm 302 towards two sides of the swinging direction respectively, the driving arm 210 and the swing arm 302 are arranged at intervals, a pressing part 211 is arranged between the driving arm 210 and the swing arm 302, an interval is arranged between the pressing part 211 and the swing arm 302 or between the driving arm 210, and the pressing part 211 can be driven by the driving arm 210 to press the swing arm 302. The driving arm 210 is used for driving the shifting fork to rotate and driving the swing rod 300 to swing in a linkage manner. In this embodiment, the pressing portion 211 is fixed to the driving arm 210, and a space is provided between the pressing portion 211 and the swing arm 302. The driving arm 210 constitutes a key plate of the switch for operation by a user. The drive arm 210 can rotate at a larger angle with a smaller stroke of the swing rod, and the switch with an ultrathin structure is realized. In other embodiments, the pressing portion 211 is separated from the driving arm 210 with a space therebetween, so that the swing arm 302 has a larger swing space.

The interval between the pressing part 211 and the swing arm 302 or the driving arm 210 is provided so that the swing arm 302 has a large swing space, i.e., the swing lever 300 can have a swing angle larger than that of the fork 200. The pressing part 211 can press the driving swing arm 302 in the pressing process of the driving arm 210, and the driving arm 210 and the shifting fork 200 simultaneously drive the swing rod 300 to rotate, so that the switch has better operation handfeel.
