Injection Molding Clamping Unit - Bee Jay Molding
Toggle Clamp. A 5-point double toggle clamp is shown in Figure 1. After amplification by the toggle mechanism, the clamping cylinder, attached to the tail platen, extends, pushing the moving platen to lock the mold halves together. We will investigate in various ways how the clamping force is generated.

Linkage (mechanical) - Wikipedia
Klann linkage is a six-bar linkage that forms the leg of a walking mechanism; Toggle mechanisms are four-bar linkages that are dimensioned so that they can fold and lock. The toggle positions are determined by the colinearity of two of the moving links. The linkage is dimensioned so that the linkage reaches a toggle position just before it folds.

Switch - Wikipedia
The word "toggle" is a reference to a kind of mechanism or joint consisting of two arms, which are almost in line with each other, connected with an elbow-like pivot. However, the phrase "toggle switch" is applied to a switch with a short handle and a positive snap-action, whether it actually contains a toggle mechanism or not.
