What is the resistance of closed plug key?

The resistance of a closed plug key typically refers to the electrical resistance measured across its terminals when it is in the closed (on) position. This resistance is usually very low, ideally close to zero ohms, allowing for efficient current flow. However, the actual resistance can vary slightly due to factors like the material quality and the design of the key. In practical applications, a very low resistance ensures minimal power loss and heat generation during operation.
