<P>PROBLEM TO BE SOLVED: To provide a seesaw switch that can reduce the number of fabrication steps with a small number of constituent parts, perform a sure switching operation and make operation feeling excellent. <P>SOLUTION: A seesaw type switch for an indoor illumination lamp assembly 10 for a vehicle has two contact portions 60A, 60B extending from a seesaw type switch knob and two bus bars 50A, 50B which are in contact with the contact portions 60A, 60B, respectively. The surfaces of the bus bars 50A, 50B which come into contact with the contact portions 60A, 60B are configured in a corrugated shape having mountain portions and valley portions, and have three valley portions. The slop surfaces of the valley portions at both the ends are more moderate than the slope surface of the valley portion at the center, and θ1>θ3>θ2 is satisfied when the slope surfaces of the valley portions at both the ends of the first bus bar 60B are set to a slope angle θ1 from the valley portion to some middle portion thereof and to a slope angle θ2 from the middle portion to the apex thereof and the slope surfaces of the valley portions at both the ends of the second bus bar 60A is set to a slope angle θ3. <P>COPYRIGHT: (C)2012,JPO&INPIT |
