Abstract

A control lever has a moulded end formed as a suitable shape - such as a ball or a cylinder (3). One the front face is a recess (3a) in which a finger may be placed. This recess may be positioned to take a finger of a right hand. The remaining surface area is formed from two flat surfaces which join to form a sharp edge to prevent handling in the reverse direction. The sharp edge may have projecting teeth and if a ball is used the remaining surface not covered by the recess is covered by small spikes.
