Snap Action Rotary Switch Adapter

A torsion spring 3 having adapter ends 3a and 3b as shown, provides an adapter 2 connecting an operating knob 4 drive mechanism to the shaft of a commercial rotary switch 1, provided with the usual detent mechanism for holding the switch in the position to which it is operated.

When the knob 4 is turned, the detent prevents the switch 1 from turning until the spring 3 twists sufficiently for the restoration force to overcome the detent force. The switch then moves rapidly to its next position with a snap action. The spring force is such that the restoration force exceeds the detent force, when the spring 3 is deflected somewhat less than the angular displacement between detent positions.
