This item came from the warehouse of my grandfather, who was an electrician. It has been in long-term storage. This is a Showa-retro dimmer switch. It's quite rare. Some items have discoloration of the body due to aging. Please examine the photos to understand the condition. Please understand that this item has been handled by someone else. Bidders who are overly concerned about condition should refrain from bidding. I will not sell these items individually. I am also listing other electrical equipment. Thank you.
