Embodiment

[0021] like figure 1 As shown, the knob-type anti-mistake switch includes 0 gears, S1 gears, S2 gears, S3 gears, Tag gears, 1st gears and 2nd gears, which are 7 gears. When the lock bolt 5 is located on the left side of the knob 3, the lock bolt 5 is on the left side; similarly, when the lock bolt 5 is located on the right side of the knob 3, the lock bolt 5 is on the right side.

[0022] like figure 2 , Figure 5 , Image 6 As shown in the figure, a knob-type error-proof switch includes a casing 1, a rotating shaft 2 axially arranged in the casing 1 and extending upward, a knob 3 mounted on the rotating shaft 2, and a rotary shaft 2 disposed between the rotating shaft 2 and the casing 1. Turn block 4. A lock bolt 5 that can move left and right is also installed on the knob 3, and two spherical pits 6 are arranged on the lock bolt 5. A compression spring 7 and a steel ball 8 against the compression spring are arranged between the inner wall of the knob 3 and the spherical...

Abstract

The invention discloses a rotary knob type anti-misoperation switch, which comprises a casing (1), a rotating shaft (2) axially arranged in the casing (1) and extending upward, a knob (3) installed on the rotating shaft (2), and The rotary block (4) is arranged between the rotating shaft (2) and the casing (1), the lock bolt (5) that can move left and right is installed on the knob (3), and the casing (1) is provided with an arc Shaped ribs (11), the lock bolt (5) is correspondingly provided with a first groove (51) and a second groove (52) that cooperate with the arc-shaped ribs (11) in different gear positions. In the present invention, by adding a locking bolt on the knob, the first groove and the second groove on the locking bolt cooperate with the arc-shaped convex ribs on the shell respectively at corresponding positions, so as to realize the anti-mistake function of the knob switch. The reliability of the switch is improved, the structure is simple, and the assembly efficiency of employees is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of automobile switches, and in particular relates to a knob type error-proof switch. Background technique [0002] Knob switches are widely used in automotive electronic equipment. In the structural design of common knob switches, the knob is usually rotated at a certain angle. Phase conduction to achieve the corresponding function output. However, the existing rotary switch generally lacks a limit mechanism, so that the switch is likely to rotate several steps continuously or the rotary knob rotates in the opposite direction during operation, and it is difficult for the rotary switch to accurately move to a preset position. [0003] For example, Chinese Patent Application No. 200810304597.3 discloses a rotary switch, which includes a base, a collar fixed on the base, a rotating body limited between the base and the collar, and a first contact body disposed on the rotating body , the second contact body ar...
