	The F-Switch is a new concept of device for the manipu-lation of large arrays of 2D CRLs or similar disc-shaped optical elements (12mm dia, 2mm thick) under high vac-uum. Unlike the well-known transfocator devices the optical elements are randomly selectable. This enables a number of potential modes of operation, including the fine adjustment of focal length by adjusting the effective lens centre position when using CRLs or the use of some positions within the array to implement filters or reference foils. Actuation and guidance is achieved within the thickness of the element, so that the overall length of the device is minimised. The device has been in user operation on the I04 MX beamline at Diamond Light Source (DLS) since 2015. Another device is being assembled for use on the I11 beamline at DLS. It is also hoped to install another device on the I03 beamline. We present details of the mechanical design of the F-Switch and some examples of its operation.

The F-Switch is a new concept of device for the manipu-lation of large arrays of 2D CRLs or similar disc-shaped optical elements (12mm dia, 2mm thick) under high vac-uum. Unlike the well-known transfocator devices the optical elements are randomly selectable. This enables a number of potential modes of operation, including the fine adjustment of focal length by adjusting the effective lens centre position when using CRLs or the use of some positions within the array to implement filters or reference foils. Actuation and guidance is achieved within the thickness of the element, so that the overall length of the device is minimised. The device has been in user operation on the I04 MX beamline at Diamond Light Source (DLS) since 2015. Another device is being assembled for use on the I11 beamline at DLS. It is also hoped to install another device on the I03 beamline. We present details of the mechanical design of the F-Switch and some examples of its operation.
