How A Spring Loaded Plunger Works

A press-fit ball plunger is a device that uses a spring to act as a force multiplier. The spring loaded plunger consists of a housing, a ball, and a spring. The ball is press-fit into the housing and held in place by the tension of the spring. When the plunger is actuated, the ball is forced against the housing, causing the housing to compress the spring. The compressed spring then drives the ball out of the housing, providing a downward force on whatever it is pressing against. This type of plunger is commonly used in applications where a large force is needed to overcome an obstacle, such as in doorstops and push-button switches.
