Ballplunger - Glossary - Technical
Glossary - Ball Plunger (Spring Plunger)
A device incorporating a housing (body) and a spring loaded ball or pin. They are used for securing an item
in a closed position, whilst requiring a certain force to be applied to allow the item to be opened. The ball
seats into a notch in an adjoining part, until such time as sufficient pressure is applied to enable the ball
to retract into the housing, thereby allowing the part being pushed to move freely from it’s closed position. (see pictures).
Ball plungers can be found here in the Hobby and Engineering Supplies online catalogue.
