Abstract

One kind of touch variable resistor structure capable of being miniaturized and reducing input unit is provided. The variable resistor has one resistor element, one conductor, one first insulating plate in one side of the resistor element and the conductor, and one second insulating plate in the other side of the resistor element and the conductor. The resistor element and the conductor are configured separately, and the resistor element may contact with the conductor by depressing the second insulating plate to produce output corresponding to the depressed position. Under the first insulating plate, depressing switches are set for the depressing operation through the two insulating plates.

Description

technical field [0001] The invention relates to a touch-type variable resistor used in various electronic instruments, in particular to a structure of a touch-type variable resistor with a switch. Background technique [0002] As the structure of the existing touch-type variable resistor, the known structure is a resistance element and a short-circuit element having a predetermined length. It has flexibility, and when the contact is pressed at an arbitrary position in the longitudinal direction, a potential corresponding to the pressed position is output (for example, refer to Patent Document 1). [0003] The structure of the existing touch variable resistor is as Figure 9 , Figure 10 shown. Figure 9 It is a cross-sectional view of a conventional touch-type variable resistor, Figure 10 It is a top view showing an example in which a conventional touch-type varistor is mounted on an operation panel of a water heater. [0004] In the figure, the operation panel 110 is a ...
