WIPO Patent Application WO/2014/133216
Kind Code:
A1
Abstract:
The present invention relates to a non-contact brake switch structure which solves problems of existing contact-type brake switches such as low durability, wherein the contact-type brake switch is damaged by the abrasion of a contact portion according to the period of use of the switch, the generation of noise, and mechanical delays due to contact failure at the contact portion and the damage to a spring when the switch is operated. The non-contact brake switch, according to the present invention, comprises: a frame fixed to a car body; a magnetic member disposed at a predetermined position of the frame; and a magnetic field sensor element disposed on the frame at a predetermined interval from the magnetic member, wherein the magnetic connection between the magnetic member and the magnetic field sensor element is released by a brake pedal when the brake is operated, and the operation of the brake switch can be determined on the basis of whether the magnetic connection is released or not.
