Rotary switch for low passive intermodulation connection

A low passive intermodulation (PIM) RF switch comprising:

• a first center conductor connected to at least one first stationary pad,
• a second center conductor connected to at least one second stationary pad,
• at least one first movable pad and at least one second movable pad electrically and mechanically connected together by a first movable pad bridge, which is further connected mechanically to a drive means configured to move about a center axis,
• wherein, in a first coupling state,
• the at least one first stationary pad is in close proximity to the at least one first movable pad and the at least one second stationary pad is in close proximity to the at least one second movable pad, to cause a capacitive coupling between the at least one first stationary pad and the at least one first movable pad and between the at least one second stationary pad and the at least one second movable pad to form an RF signal connection between the first center conductor and the second center conductor via respectively-corresponding stationary and movable pads,
• wherein the switch is configured to prevent a galvanic contact between said stationary and movable pads by any of (i) having said pads coated with a non-contacting paint;
• (ii) having said pad carry an anodized isolating layer;
• and (iii) having said pads separated from one another with a plastic material;
• and
• wherein at least one of the movable pads is configured to be repositioned by at least one of (i) displacement in parallel to a plane defined by such pad, and (ii) tilt with respect to a plane defined by such pad.
