Introduction

Terminal blocks are items used to make connections between two or more components in an electronic circuit. A specialized type of terminal block is a jumper. Jumpers contain a conductive material, usually metal, that allows electrical charge to pass from one terminal to another. Although similar in appearance to terminal blocks, jumpers have different applications and working principles.

Applications

Jumpers are used in a variety of electrical applications. They are most commonly used to configure circuits. When used in this capacity, the jumper acts as a bridge between two points in the circuit. This allows the user to change the configuration of the circuit without having to alter the wiring.Jumpers are also used to provide a stable connection between two conductive objects. They can provide a stronger connection than soldering due to their stable, replaceable nature.

They are also commonly used to bypass sections of a circuit. This allows the user to turn off specific sections of the circuit while the circuit is still powered on. Jumpers can also be used to test the operation of a circuit by providing continuity between two points and allowing current to pass.

Working Principle

The working principle of jumpers is relatively simple. A jumper consists of a replaceable bridge component made of an electrically conductive material such as copper or silver. This bridge component is inserted into two contacts on opposite sides of the circuit, forming a connection between them. The replacement of this bridge component can easily be done by sliding it out of the contacts and inserting a new one that is more suitable for the application.

The electrical current then flows from one contact to the other through the bridge component. The force of the electrical current pushes against the bridge component, creating a secure connection between the two contacts. This secure connection allows electrical current to pass from one contact to the other with minimal resistance.

Jumpers also offer the advantage of being easily replaceable. If a bridge component becomes damaged or worn out, it can be replaced without the need for any specialized tools. This allows for quick and easy repairs to be made to a circuit without the need for extensive rewiring.

Conclusion

Jumpers are a type of terminal block that are used for a variety of applications. They consist of a replaceable bridge component that allows current to pass from one contact to the other. They are most commonly used to configure circuits, provide a stronger connection between two conductive objects, and bypass sections of a circuit. The working principle of a jumper is simple and it offers the advantage of being easily replaceable.
