pätkäjohtojen

Pätkäjohto, often referred to as a jumper wire or patch cable in English, is a short, insulated electrical wire used to connect components in an electronic circuit or system. These wires are typically made of copper and are covered with a plastic or rubber insulation. Pätkäjohdot are crucial for prototyping, testing, and making temporary connections. They are commonly found in breadboards, where they facilitate the creation of temporary circuits without soldering. The length of a pätkäjohto can vary, but they are generally short, ranging from a few centimeters to about a meter.

The primary function of a pätkäjohto is to bridge gaps between terminals or connection points, allowing electrical current to flow. They can be used to connect different parts of a circuit board, link separate electronic modules, or even to bypass a faulty component for diagnostic purposes. Due to their temporary nature, pätkäjohdot are not typically used in permanent installations where reliability and long-term durability are paramount. However, their ease of use and flexibility make them indispensable tools for hobbyists, engineers, and technicians working with electronics. They come in various forms, including single wires with stripped ends, wires with pre-attached connectors (like Dupont connectors), and specialized ribbon cables.
