Automatic gearboxes from year to year are gaining more and more popularity among compatriots. Surely, even those who have never had a car paid attention to one curious feature. Namely, that some automatic transmission models are switched using a lever that is moved back and forth, while other models - using a lever mounted on a zigzag. Is there any difference between such boxes besides visual? Perhaps one of them is better.
First of all, it is worth noting that the development of automatic transmission selectors (shift levers) has a rather long and rich history. In fact, many more types of derailleurs exist and are used in the automotive industry than straight and zigzag derailleurs. In the gearboxes themselves, there is no fundamental difference based on the difference in selectors.
For example, until the 1990s, in cars (predominantly American production) with automatic transmission, the selector the gear shift was located on the steering block, and not at all where most of us are used to it see. This solution made it possible to install a sofa for three people in the car in the driver's seat, instead of chairs for only two people. At the same time, the selector switch was difficult enough to change gear, the lever first had to be pulled towards itself "from" the steering block. Since the 1960s, the type of selector located on the dashboard has also been quite popular.
The floor switch for automatic transmission was first introduced in 1953 on the Chevrolet Corvette. Today, it is this variety that is most popular in cars that go to the Old World market. The floor selector is most popular due to the fact that it looks and functions more familiar to most motorists moving from "mechanics". This implementation was necessary primarily in order not to scare away the buyer.

As you might have guessed, the straight and zig-zag selectors are just variations on the foot switch for an automatic transmission. The shape of the slot for the lever in this case is dictated by the design features. If the groove under the lever is straight, it means that it will have a release button located on the side (or in front) under the thumb on the “cap” of the switch. It is needed in order to prevent accidental switching of the automatic transmission while driving. A kind of "fuse".

Accordingly, if the groove under the lever is zigzag, then it most likely will not have a button. Since the zigzag already works as a safety device against arbitrary switching. However, with this design, there are also automatic transmission models, in which the lever, when shifted from the "R" position, should be slightly drowned so that it moves. This is the fundamental difference between the two selectors - the organization of the protection mechanism.
It's winter outside the window, which means that the driver is in trouble every now and then due to bad weather. For example, how many problems are caused by icing of the windshield in the morning. But we found a simple way to remove ice from a car windshield without harming it.
