This wing nut is used for operating and securing a light switch in classic vehicles. The shape gives grip for manual adjustment without tools. The part fits specific versions of Citroën passenger cars from an older series. The dimensions follow a common thread combination with a length suitable for installation in the dashboard or a panel. The material is selected for stable connection and reliable locking of the switch. The wing shape allows simple removal for maintenance or replacement of electrical components in the vehicle wiring system. The design supports repeated assembly and disassembly in regular workshop service.
