Abbatron 2454 is a type of electromechanical switch used in electronics. It is typically an SPDT (single pole double throw) or DPDT (double pole double throw) switch and is used to control the flow of electricity between two components or circuits. The switch is mounted on a printed circuit board and consists of two parts, a body and a lever arm. The body of the switch contains two sets of contacts, one set made of copper and the other of brass. When the lever arm is moved, the contacts associated with that lever arm make contact with each other, allowing electricity to flow through the circuit. The switch can be used for a variety of applications, such as controlling power, switching signals and controlling the direction of a motor.
