ABSTRACT:
A lever mounted on a support for pivotal movement between two end positions is acted upon by a toggle spring connected at its opposite ends to the lever and the support to bias the lever away from a centre position of unstable equilibrium towards its two end positions. In the invention, instead of using a conventional coil spring, the toggle spring is constructed a leaf spring.
