Abstract
A steering wheel horn switch includes two contact members and a support member, which supports the contact member and is formed from a light metallic material, and the contact member and the support member are electrically conducted to each other in such a manner to form a horn operating circuit. An electric conductor having electrical conductivity, which is higher than the electrical conductivity of the support member, is disposed between the contact member and the support member in such a way as to come in contact with both the contact member and the support member. The electric conductor is in contact with the support member so that the contact area therebetween is larger than the contact area between the contact member and the support member in the case when the contact member is singly brought into contact with the support member, or so that the electric conductor is brought into contact with the support member by being pushed by the support member.
