<p>Provided is an improved key switch for vehicles which can control the generation of heat from the contacts without increasing the size of the switch structure itself. The key switch may comprise a rotor, which rotates in accordance with the insertion and rotation of a key, a plurality of fixed contacts provided in a terminal support plate, a plurality of moveable contacts carried by the rotor which cooperate with the fixed contacts according to the angular position of the rotor, and a plurality of terminal plates for connecting the fixed contacts to onboard electric equipment and an onboard battery via a coupler. The terminal plates include a redundant or idle terminal plate which is commonly connected to the terminal plate for power supply, and promotes the dissipation of heat from the terminal plate for power supply, and increases the rigidity of the structure for supporting the coupler.</p> |
