Abstract
In a tactile-feedback rotary electrical component, a first U-shaped spring is mounted in a recessed holding portion formed in a housing along the axial direction of an operating member. When the operating member is rotated, a protuberance formed on the first U-shaped spring engages with and disengages from recesses formed in the operating member, thereby producing tactile feedback.
