Plug in switch. 6.2x6.2x2.5. Red handle four pin plug in. Key switch. There are many sizes of light touch switches, among which the height of the light touch switch depends on the same size. Many light touch switches look the same, but their thickness (height) is different. Below are several representative sizes of touch switches. Among them, the 2x3 and 2x4 light touch switches are also known as the Little Beibei four foot patch type light touch switches. His height is generally 3.5mm. There are two main heights for the 3x3 touch switch, with dimensions of 0.8 and 1.5 in height. It has three functions: environmentally friendly, high-temperature resistant, and waterproof, with only patch touch switches available. There are three main types of 3x4 touch switch sizes and heights: 1.8, 2.5, and 3.0. There are several types of touch switches, including environmentally friendly, dual spring type, and two-pin patch. The size and height of the 3x6 touch switch are mainly 0.8, 3.5, and 3.8, belonging to the side press series of touch switches. There are two foot side press and four foot side 3x4 touch switch sizes and heights are mainly 1.8, 2.5, and 3.0, and there are several types of touch switches, including environmentally friendly, dual spring type, and two foot patch.

There are three main sizes and heights of 3x6 touch switches: 0.8, 3.5, and 3.8. They belong to the side press series of touch switches and have two foot side press and four foot side press. The dimensions and heights of 4x4 touch switches mainly include: 1.5, 1.7, 2.0, 2.3, 2.5, 3.0, 3.5, 3.7, 4.3, and 6 height patch touch switches, usually with four foot patch touch buttons. 4.5x4.5 is divided into three types of touch button switches: plug-in, patch, and edge triangle:

The plug-in 4.5x4.5 touch switch has two main sizes and heights: 3.8 and 5, and is generally a four pin plug-in touch switch.

The size and height of the 4.5x4.5 patch touch switch mainly include: 3.2, 3.8, 4.0, 4.5, 4.8, 5.0, 5.5, 6.0, and 7.0. There are nine types of patch touch switches, generally only four feet, also known as four foot patch switches.

The dimensions and heights of the 4.5x4.5 edge triangle light touch switch mainly include: 3.8, 4.3, 4.8, 5.0, 5.5, 7.0, 8.0, among which the height edge triangle light touch switch button, also known as the edge triangle light touch switch. 6x6 is divided into two types of light touch switch buttons: patch and plug-in. The size and height of the 6x6 patch light touch switch mainly include: 4.3, 4.5, 5, 5.5, 6, 7, 8, 9.5, 10, 12, and 13 eleven types of height patch button switches, mainly four foot buttons. The dimensions and heights of the 6x6 plug-in touch switch mainly include: 4.5, 5.5, 6.5, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, and 19. There are eighteen types of height plug-in touch button switches, usually only four pin plug-in. The 6.2x6.2 touch switch is divided into two types: patch and plug-in. The size and height of the 6.2x6.2 patch touch switch mainly include: 2.5, 2.7, 3.1, 3.7, and 5.1. There are five types of four foot patch touch button switches, which are generally four foot and require a five foot patch.

The height of the 6.2x6.2 plug-in touch switch mainly includes three types of four pin plug-in touch switch buttons: 2.5, 2.7, and 3.1, which are generally four pin plug-in.

Secondly, there are two special touch button switches, 10x10 and 12x12, with heights of 4.3, 5.0, 5.5, 6, 7, 8, 9, 9.5, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 26. 10x10 and 12x12 are large point touch button switches that are rarely used.

The working principle of a light touch four foot button switch is actually similar to that of an ordinary button switch. It is composed of a combination of normally open and normally closed contacts. In a four foot button switch, the normally open contact acts as a circuit that is connected when pressure is applied to the normally open contact; When this pressure is lifted, it returns to the original normally closed contact, also known as disconnection. The force of pressure is the action of using our hands to open and close buttons. In summary, the working principle of the four legged button switch is still easy to understand. First, measure any two legs in the four corners to determine which corner is conductive and which corner is disconnected. Press the button and measure any two legs to determine which corner is conductive and which corner is disconnected. Start disconnecting. Press the button to determine which corner is conductive and which corner is disconnected. The conductive legs can be used as the two corners for soldering. Tap the switch specifications and dimensions. The above figure shows the size and circuit diagram of the four foot tap switch. Based on experience, Generally, direct welding can be carried out on just the diagonal corner. The working principle of a button switch is that when the button is pressed, the two patches come close, which means they are conductive; When released, the patch separates, which means it is disconnected.
