SWITCH DEVICE
Document Type and Number:
Japanese Patent JPH06283993
Kind Code:
A
Abstract:
PURPOSE: To provide the proximity detection mode that detects proximity to a switch by a conductor to the switch device which applies switching to the switch in the direct machine operating mode. CONSTITUTION: Lands 4, 5 insulated with each other and a conductive elastic capsule 6 in contact with the land 4 and covering an upper part of the land 5 are formed on a broadcast 1 as a switch I. A generator 9 is connected to the switch I and a high frequency signal is applied to the switch I. The switch I is connected to a circuit that measures a change in a high frequency signal and the proximity of a conductor is detected by the change in the high frequency signal. Thus, a conventional key pad or a touch enable pad is used for a matrix type key board.
