Patent number: 6320499Abstract: The present invention relates to a brake signal sensor device which is electrically connected to a warning light by a transfer wire. The brake signal sensor device includes a body, and a cover mounted on the body. The body defines a receiving chamber for securing a contact switch whose one side is provided with two spaced guide plates. A pull wire is used to pull an elastic member to displace a conducting member, such that the contact switch can produce a start signal which is transferred to the warning light, whereby the warning light secured on the bicycle emits light, thereby enhancing the safety of riding the bicycle. The brake signal sensor device may be easily fixed on the brake cable adjacent to the brake lever by a fastening strap without having to be mounted on the brake pad.Type: GrantFiled: March 16, 2001Date of Patent: November 20, 2001Inventor: Ching-Yung Wang
