Toggle with Single and Double Action
Product Code : JA-PLE-4195
The Toggle with Single and Double Action (SKU JA-PLE-4195) is a working model of a standard toggle mechanism, the linkage behind toggle presses and clamps. Two links meet at a joint driven by a crank and connecting rod, and the stroke setting decides whether the slider advances once or twice per revolution. This toggle mechanism model is one of a series of sixteen A3 board-mounted mechanisms for theory of machines, applied mechanics and engineering drawing teaching.
Specifications
The toggle consists of two links AB and BC, with C fixed and A a slider; the joint B is driven by a crank and connecting rod, which for single action limits B to the line AC, while a longer stroke carries B past AC to give a second advance of A per revolution.

Applications of the toggle mechanism model
The model shows students how the toggle links straighten towards the line AC, giving a short, slow final movement of the slider, and how lengthening the crank stroke changes single action into double action.
- Demonstrating single and double toggle action from one crank drive
- Tracing the path of joint B and the displacement of slider A
- Explaining the toggle principle used in presses, clamps and crushers
- Studying how changing the crank stroke changes the output motion
- Theory of machines and applied mechanics classes in polytechnics, TVET institutes and engineering colleges

Frequently asked questions
What is the difference between single and double action?
In single action the crank limits joint B to the line AC, giving one advance of A per revolution; with a longer stroke B passes AC and A advances twice per revolution.
How is the toggle driven?
The joint B between links AB and BC is driven by a crank and connecting rod.
