mygtukas

Mygtukas is the Lithuanian term for a button. It refers to a small control element designed to be pressed or touched to operate equipment or software. In electronics, a mygtukas usually denotes a push-button or switch. It can be mechanical, with metal contacts that close a circuit when pressed, or capacitive or optical in some devices. It can be momentary, providing a signal only while pressed, or latched, maintaining its state after a press until pressed again.

Physical push-buttons are common in keyboards, remote controls, calculators, and control panels. A tactile switch is a type of mechanical push-button designed to provide feedback when actuated. Illuminated buttons include LEDs to indicate status or improve visibility in the dark, and models with IP ratings are designed to resist dust and moisture.

The term also covers digital or on-screen buttons used in software interfaces. On-screen buttons mimic physical controls but respond to touch rather than mechanical actuation, enabling user interaction on smartphones, tablets, and computers.

In design and accessibility, button size, actuation force, travel distance, and labeling contrast affect usability. Reliability is often described by cycles-to-failure or similar durability metrics, and engineers consider environmental conditions such as temperature and moisture.
