Claims

[Claims for Utility Model Registration] A steering wheel that presses the horn pad 2 against the boss plate 1 to move the movable contact 3d together with the horn pad 2 and bring it into contact with the fixed contact 4f, thereby closing the horn circuit and sounding the horn. In the horn switch, an insulating member 5 is attached to the boss plate 1,
A first locking groove 5c and a second locking groove 5 are provided in the insulating member 5.
e and 5f, respectively, a fixed contact support member 4 is inserted into the first locking groove 5c of the insulating member 5 to lock and hold it, and the fixed contact support member 4 is provided with the fixed contact 4f, One end 3b of the U-shaped movable contact support member 3 is inserted into the second locking grooves 5e, 5f of the insulating member 5, and is locked and held in a state insulated from the fixed contact support member 4, while the movable Other end portion 3 of contact support member 3
a is provided with the movable contact 3d, and the movable contact 3d is arranged so as to be able to contact the fixed contact 4f against the biasing force of the movable contact support member itself, and the other end 3a is provided with the leg portion of the horn pad 2. A horn switch for a steering wheel, characterized in that 2a is brought into pressure contact.
