Vehicle accessory touch switch
First Claim
1. A vehicle accessory touch switch, comprising:
- a touch section having a sensor conductor plate which is touched by an operator,a capacitance measurement section which measures a change in electrostatic capacity of the sensor conductor plate to a ground conductor as a sensor conductor plate capacity change, anda control section which controls accessory equipment mounted on a vehicle according to comparison between the sensor conductor plate capacity change and a control judgment value, wherein;
the vehicle accessory touch switch controls the accessory equipment according to a touch by the operator to the touch section,a sub-conductor plate is disposed independent of the sensor conductor plate,the capacitance measurement section measures a change in electrostatic capacity between the sub-conductor plate and the ground conductor as a sub-conductor plate capacity change, andthe control section decides the control judgment value according to the sub-conductor plate capacity change measured by the capacitance measurement section.

Abstract
A touch switch for controlling accessory equipment of a vehicle in such a manner that malfunctions caused by factors such as changes in atmospheric conditions, receipt of an electromagnetic impulse, or the like can be avoided. A vehicle accessory touch switch comprises a touch section having a sensor conductor plate which is touched by an operator, a capacitance measurement section which measures a change in electrostatic capacity of the sensor conductor plate to a ground conductor as a sensor conductor plate capacity change, and a control section which controls accessory equipment according to comparison between the sensor conductor plate capacity change and a control judgment value, wherein the vehicle accessory touch switch controls the accessory equipment according to an operator touching the touch section, a sub-conductor plate is disposed, the capacitance measurement section measures a change in electrostatic capacity between the sub-conductor plate and the ground conductor as a sub-conductor plate capacity change, and the control section decides the control judgment value according to the sub-conductor plate capacity change measured by the capacitance measurement section.
