Touch rotary switch

Abstract

The invention discloses a touch rotary switch and especially relates to a switch that is capable of turning on and off an external power supply or gradually adjusting a power supplying level of the external power supply based on the rotation path by utilizing a touch way. An induced surface is arranged at the top of a housing; a touch circuit board is arranged inside the housing; a touch circuit layer surrounding zone at the top surface of the touch circuit board is divided into a plurality of induction zones; and a plurality of first light-emitting assemblies are arranged in the induction zones of the touch circuit layer in an annular mode. The user touches the switch along the periphery of the induced surface and thus the touch circuit layer of the induction zones are triggered in sequence, so that the touch circuit layer of the triggered induction zones controls the first light-emitting assemblies corresponding to the induction zones receiving the triggering to carry out light emitting; and a coded signal for controlling power supplying of the external power supply is outputted based on the triggered induction zones, thereby improving the using convenience and the durable service life.

Description

technical field [0001] The invention relates to a rotary switch, in particular to a touch-type rotary switch which can be turned on, off or gradually adjusted to the level of external power supply by touch and according to the path of rotation. Background technique [0002] Whether it is 3C electronic products, communication devices or home appliances, it is often equipped with a rotary switch. The rotary switch is generally used for switching the power supply of the circuit and adjusting the high and low levels of the power supply. It is used to adjust the speed and strength of the electrical appliance. , such as the speed of the electric fan, the strength of the air conditioner, the volume of the stereo, the brightness of the light, and the signal strength of the wireless machine, etc. [0003] Most of the traditional rotary switches are composed of a mechanical structure, which has a switch body and a rotating shaft pivoted on the switch body and can be rotated by the use...

AI Technical Summary

Problems solved by technology

[0005] The main purpose of the present invention is to provide a touch-type rotary switch that can be opened, closed or gradually adjusted the power supply level of the external power supply according to the rotating path in a touch manner, so as to overcome the inaccurate control accuracy of the traditional mechanical rotary switch. problems, and to overcome the long-term frequent use of mechanical rotary switches, which may easily cause problems such as slack, poor movement, damage, etc. among the internal components of the switch, as well as the problems that it is easy to stick or deposit external dust and dirt and affect its normal operation, and then Improve durability
