Feb 13, 2025 · An over-center mechanism is a type of mechanical linkage that provides a locking or latching function by utilizing a specific geometric configuration. Most of us instantly know when we …

The basic principle of an over-center linkage is that it uses a mechanical advantage to create a locking or latching mechanism by utilizing the point at which the linkage goes over-center.

Oct 21, 2025 · The key to their reliability is a calibrated lever and pivot mechanism that passes a locking “over‑center” point, creating strong clamping force and resisting accidental opening. The principal …

If you only learn to design with one mechanism, make it an over centre mechanism. In my opinion, this is one of the most versatile and effective mechanical systems you can utilise.

This locking mechanism ensures the clamp remains secure and does not release unintentionally. The term “over center” refers to the position of the linkage system in relation to the pivot points.

May 1, 2024 · It’s an over-center mechanism. I can’t think of any engineer or mechanic I’ve ever known who wouldn’t identify it immediately as such. It’s commonly used to latch or lock mechanisms in …

Jun 18, 2025 · When the latch is closed, the linkage system moves until the pivot point of the levers crosses a specific line (the "center"). This creates an over center lock point. Once it reaches this over …

Choose from our selection of over-center latches, including draw latches, latch-style clamps, and more. Same and Next Day Delivery.

The present disclosure relates generally to over-center spring mechanisms. Over-center spring mechanisms are typically used to mechanically hold a pivoting structure in selected resting...

The over center linkage is a kinematic arrangement of rigid links connected by joints, designed to lock or hold a mechanism in a specific position with minimal or no input force.
