Embodiment
[0021] Such as figure 1 As shown, the knob type anti-misoperation switch includes 7 gears: 0 gear, S1 gear, S2 gear, S3 gear, Tag gear, 1 gear and 2 gear. When the lock bolt 5 is located at the left side of the knob 3, the lock bolt 5 is at the left gear; similarly, when the lock bolt 5 is at the right side of the knob 3, the lock bolt 5 is at the right gear.
[0022] Such as figure 2 , Figure 5 , Figure 6 As shown, a rotary knob type anti-misoperation switch includes a housing 1, a rotating shaft 2 axially arranged in the housing 1 and extending upward, a knob 3 installed on the rotating shaft 2, and a rotating shaft 2 arranged between the housing 1 Turn block 4. A locking bolt 5 that can move left and right is also installed on the knob 3. Two spherical pits 6 are arranged on the locking bolt 5. A compression spring 7 and a steel ball 8 that is offset against the compression spring are arranged between the inner wall of the knob 3 and the spherical pit 6. , this mome...

The invention discloses a rotary knob anti-misoperation switch, which comprises a housing (1), a rotating shaft (2), a rotary knob (3) and a rotating block (4), wherein the rotating shaft (2) is axially arranged in the housing (1) and extends upwards; the rotary knob (3) is arranged on the rotating shaft (2); the rotating block (4) is arranged between the rotating shaft (2) and the housing (1); a lock plunger (5) capable of moving left and right is arranged on the rotary knob (3); a circular convex rib (11) is arranged on the housing (1); and a first groove (51) and a second groove (52), which are matched with the circular convex ribs (11) at different gears, are correspondingly formed in the lock plunger (5). The lock plunger is additionally arranged on the rotary knob; the first groove and the second groove in the lock plunger are respectively matched with the circular convex ribs on the housing at the corresponding gear, so that the anti-misoperation function of the rotary knob switch is achieved; the reliability of the switch is improved; the structure is simple; and the assembly efficiency of the staff is greatly improved.
Description
technical field [0001] The invention belongs to the technical field of automobile switches, in particular to a knob type anti-misoperation switch. Background technique [0002] Knob switches are widely used in electronic equipment of automobiles. In the structural design of common knob switches, the knob is usually rotated by a certain angle, and the knob reaches the designated gear according to the designed motion trajectory, so that the moving contact piece and the static contact piece inside the switch Phase conduction to achieve the corresponding functional output. However, existing rotary switches generally lack a limit mechanism, so that the switch is prone to continuous rotation of several gears or the rotary knob rotates to the opposite direction during operation, and it is difficult to accurately move the rotary switch to a preset position. [0003] For example, Chinese patent application number 200810304597.3 discloses a rotary switch, which includes a base, a col...
