U28TZQI

Toggle Switches

The U28TZQI is a type of toggle switch that is mainly used in 4V applications. It is a single pole toggle switch with a double-throw (SPDT) switch contact that has a normally-open (NO) and normally-closed (NC) setting. It has a center-off terminal, allowing it to be turned both ways. It has a wide variety of uses in low-voltage applications, including low-voltage lighting, doorbells, light switches, and many others.

The U28TZQI has an external handle that when moved up or down causes the switch to make or break a connection between two or more terminals on the toggle switch. This type of switch is useful in applications where there is a need to switch between two circuits and to alternate between one circuit and another. Typically, this type of switch has one pair of terminals for the input, one pair for the output, and another pair for the toggle switch mechanism. In this way, the switch is able to isolate and connect the different components.

When the handle of the U28TZQI switch is moved up or down, a metal bar inside the switch will be pushed or pulled, closing or opening the switch. This metal bar consists of two pins that are attached to metal disks. When the metal bar is closed by pushing or pulling it, the metal disks move and make contact with the two pairs of contacts on the switch, thus closing the switch. When the metal bar is opened, the contacts are freed and the switch is open.

Another advantage of the U28TZQI is its flexibility. Because it is a double-throw (SPDT) switch, it can be used in a variety of electrical applications. In low-voltage applications, where two or more circuits must be connected, the U28TZQI is ideal. It can also be used in applications where both the input and output need to be isolated. It is commonly used in the automotive industry for low-voltage lighting, power windows, and other applications.

The U28TZQI toggle switch is also easy to install. Due to its small size and simple construction, it can be installed in tight spaces. Additionally, it is applicable to a variety of mounting configurations, including DIN rail, screw terminal, and panel mount. Its simple design also makes it easy to maintain and repair.

In conclusion, the U28TZQI is a sophisticated and versatile toggle switch that offers multiple switching options in 4V applications. Its SPDT switch contact and center-off terminal make it ideal for a variety of low-voltage applications, and its flexibility and easy installation make it a preferred choice among electrical engineers and technicians.
