Abstract
In a vehicular lever switch having a resistor at a fixed contact plate to be combined with a pivoting knob, when a passenger charged with static electricity touches the lever, the resistor is to be prevented from being damaged. A fixed contact plate is arranged with a resistor and conductors and extended from both ends thereof in a ring-like shape to constitute a fixed contact. Further, an extended portion extended in a circular arc shape is formed on an outer side of the resistor with a gap from the conductor. Even when the hand of a passenger charged with static electricity touches a vicinity of a pivoting knob and the static electricity is applied to the fixed contact plate, the static electricity flows to the extended portion and is discharged via the conductor and a terminal. Thereby, the resistor is not damaged by static electricity. Further, it is not necessary to ensure a distance from an end edge of the pivoting knob to the fixed contact plate to be long in order to avoid propagation of static electricity and therefore, a degree of freedom of a shape of the lever can be enhanced.
