Description
Technical Field
The utility model belongs to the switch field, specific knob touch switch that says so.
Background
Knob switches are widely used in various electronic and electrical devices as switches with functions of outputting signal commands. At present, a knob switch mainly comprises a push type coding switch, a circuit board and a knob cover. The coding switch is arranged on the circuit board, the knob cover is sleeved on the coding switch, a user can realize the output of a signal instruction by rotating the knob cover, and the knob cover is pressed to realize the function control. Because some electronic and electrical equipment weight are lighter like electric kettle, directly promote electric kettle easily when pressing the knob lid and lead to can't reaching the effect of pressing, just so need support electric kettle with the hand and make it unable displacement press the knob lid again, it is comparatively troublesome. In order to solve the problems, some manufacturers design a rotary touch switch, which is composed of a non-pressing type coding switch, a touch circuit board, a main circuit board and a knob cover, wherein a touch sensing piece is arranged on the touch circuit board, the non-pressing type coding switch is arranged on the main circuit board, the touch circuit board is connected with the main circuit board through an electric wire, the touch circuit board is arranged below the knob cover, the touch sensing piece is contacted with the knob cover, the knob cover is sleeved on the non-pressing type coding switch, the knob cover can be rotated to output a signal instruction when the rotary touch switch is used, the surface of the knob cover is touched, a touch signal can be transmitted to the main circuit board through the touch sensing piece, and the function control of electronic and electrical equipment is realized. Because this kind of knob touch switch links together touch circuit board and total circuit board with the electric wire, can drive the electric wire and twist when rotating the knob lid, so the rotation range of knob lid is limited, has caused circuit control's limitation, and long-time rotation also can accelerate the ageing knob touch switch that leads to of electric wire and become invalid.
SUMMERY OF THE UTILITY MODEL
In view of the defect that current knob touch switch exists, the utility model aims to solve the technical problem that: the knob touch switch is simpler in structure and unlimited in rotation range.
In order to achieve the above object, according to one aspect of the present invention, the present invention is realized by the following technical measures: a rotary knob touch switch comprising: circuit board, knob lid and touch-sensitive piece, its characterized in that:
a switch is arranged on the circuit board, and a switch column is arranged at the upper end of the switch;
the touch sensing piece is a hollow structural piece made of a conductive material;
the knob lid bottom surface opening is inside hollow, is equipped with the grafting post in the knob lid, grafting post cavity forms the inserting groove, and the grafting post passes touch-sensitive spare and makes the constant head tank cover on the switch post of switch, and top surface in touch-sensitive spare one end is being supported to the knob lid simultaneously, and another pot head is in the outside of switch.
Further, the touch sensing member is a metal spring.
Further, the switch is a non-push type coding switch or a potentiometer switch or a rotary gear switch.
Compared with the prior art, the utility model has the advantages of: the structure of the knob touch switch is simplified, the knob touch switch is not limited by a rotation range, and can be infinitely rotated clockwise or anticlockwise to provide continuous output signals for a circuit, so that the control range of the circuit is enlarged, and meanwhile, the manufacturing cost of the knob touch switch can be reduced.
