Abstract
A variable position detent mechanism for latching a control lever at an infinite number of operating positions includes a semi-circular member connected to a support so that its axis coincides with the pivot of the control lever. A pair of electric detent coils are connected to the lever at a location adjacent the semi-circular member so that when the detent coils are energized they operate co-axially sandwiching the semi-circular member securing the lever with respect to the semi-circular member.
