Switches and Pushbuttons: Basics for Microcontrollers and Electronics Projects
Switches and pushbuttons are among the most important control elements in electronics. They are used to close or interrupt circuits – manually, reliably, and in various forms. In combination with microcontrollers such as the Raspberry Pi or Arduino, they enable interaction between humans and machines, for example to control LEDs, motors, or displays.
While a switch maintains its state, for example ON or OFF, a pushbutton is only active as long as it is pressed. This distinction is crucial for the behavior of inputs in software projects, machines, or control panels.
Typical areas of application include DIY electronics projects, robot control systems, industrial applications, or arcade controllers.
Typical Switches for Microcontroller Projects
Switches are available in numerous variants depending on the application and mechanical design. The toggle switch is particularly common. It is flipped and remains in the selected position. Ideal for power supply or mode switching.
A rocker switch works similarly but has a flatter design and is often found in devices or power strips. Slide switches are moved linearly and are often found on circuit boards for configuration. DIP switches, in turn, consist of several small switches in one unit and are used for addressing or setting operating modes directly on printed circuit boards.
All of these switch types can be easily integrated into prototyping or IoT projects and are mechanically robust as well as easy to wire.
Pushbuttons for Precise and Temporary Inputs
Pushbuttons and tactile switches, also called momentary switches, are types of buttons that only send a signal while being pressed. They are compact, reliable, and ideal for tactile inputs, for example to trigger an action or to navigate menus.
Tactile switches are often soldered directly onto circuit boards and are characterized by their small size. Variants with different button heights and actuation forces allow precise adaptation to your project. Pushbuttons with larger housings and terminal connections are particularly suitable for external control panels or arcade projects.
All pushbuttons can be easily read by a microcontroller and offer a long service life for many switching cycles. Ideal for user interfaces and simple control functions.
