Tact Switch
Tact switch is sometimes called a button. This button initiates a short circuit or opening of an electrical element. It consists of two plates. Pressing it means that the circuit is closed so that current can flow. An open circuit is when the plates are not in contact with each other, then the current cannot flow through the circuit. We can distinguish many types of switches, among which are those operated manually, such as keyboard buttons or even light switches. There are also switches in the form of modules operated by moving objects, which include, for example, sensors or doors (in commercial centres, offices etc.). Tact Switches with sensors such as temperature or pressure are often used in Arduino modules control systems. They are also used in automation and complex electronic systems. In Botland store you can find switches in different shapes and sizes. They also take different colors, so we can adjust them to the project both in terms of functionality and visual aspects.

Tact switch buttons for integration in electronic devices
Tact switches ( tactile switches) are buttons that most often contain or (less often) open an electrical circuit when touched appropriately - by gently pressing the top part. These types of buttons are monostable switches - they have only one stable position (default state) - they only change their position when pressed. When you stop pressing the button, it returns to its default configuration. This makes it suitable, for example, for controlling the Arduino module or communicating with other microcontrollers.

Compact microswitches for prototypes
Switches are an essential element of all prototype devices . Compact tact switches are an indispensable component of every module for testing digital circuits - they allow communication with a microcontroller. Even if the electrical device you are creating does not have to have any user interface, it should still have at least one button implemented - a system reset button, used to reset the processor in the system. This is not a problem, even in miniaturized Internet of Things devices - in our store you will find miniature tact switches dedicated to implementation in this type of devices.
A wide selection of button shapes and sizes
Tact switches are manufactured in a wide range of shapes and sizes . Miniature buttons are available, dedicated to implementation in compact devices where space is limited. On the other hand, our store's offer also includes buttons of an ideal size for use, e.g. on a breadboard, together with, for example, an Arduino module. Their size and shape allows for comfortable pressing while testing algorithms.
Tact Switch - FAQ
Classic tact switch buttons have two double (repeated) pins running through the entire button housing. To connect the button to the system, you only need to use two adjacent pins - they will be shorted when you press the button button.
The tact switch button is equipped with a small, flexible metal dome that bends and "jumps" under the pressure exerted by the plastic pusher. The deflection of the plate causes the two flat contacts located just below it to short-circuit, which allows current to flow between the button pins.
