Abstract: A switching circuit includes: an input/output terminal section including four SW terminals; lines connecting between these terminals; switches disposed in paths of the respective lines; and diodes disposed in the paths of the respective lines. The switches are single-pole switches. The diodes are connected to normally closed terminals of the switches, respectively.

Abstract: A bicycle illumination conductor assembly includes a primary plate coupled the bicycle axle. A secondary member is coupled to the bicycle and to the primary plate. A front light emitter is coupled to a front of the bicycle and to the secondary member. A rear light emitter is coupled to a rear of the bicycle and to the secondary member. The rear light emitter selectively emits a beam of light so the rear light emitter may be visible to an observer. A wheel light emitter is coupled to a spoke on the bicycle and to the primary plate. The front light emitter, the rear light emitter and the wheel light emitter selectively emits a beam of light so the bicycle may be visible to an observer. A power supply is coupled to the front light emitter and is operationally coupled to the front light emitter and the rear light emitter.

Abstract: A bicycle light assembly includes a body having a light end and a clamp end. A resilient member is pivotably connected to the body and has a clamp portion which is cooperated with the clamp end of the body to be connected with the brake cable. When braking, the resilient member is pivoted relative to the body and activates the light unit in the light end of the body. An isolation ring is located between the light member of the light unit and the battery to increase the sensibility of the light unit.

Abstract: A handlebar-mounted-bicycle-brake-component having a bicycle bell drum mounted on the cable housing and a bell striker mounted on the brake lever. The bell is rung by quickly releasing the brake lever. An analogous concept is having an electrical switch mounted to replace the bell.

Abstract: A parking brake switch for a vehicle including a switch having a contacting surface, the switch being positioned between an actuated state and a deactuated state, a first contact connected to a brake valve associated with an electro-hydraulic braking system, a second contact connected to a pair of electronic control modules, and a third contact connected to the pair of electronic control modules and a coil, the contacting surface being adapted to engage all of the contacts when the switch is in the actuated state.

Abstract: 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.
