Rotary multiple-gear switch

Abstract

The invention discloses a rotary multiple-gear switch which has a simple structure, a small volume and low cost and can position rapidly and correctly by one-way rotation. The rotary multiple-gear switch comprises a shell, a switch rotor (3) and a rotary gear adjustment device; the rotary gear adjustment device is connected with both the switch rotor (3) and the shell; the switch rotor (3) is used to adjust the gear when rotating relative to the shell; the rotary gear adjustment device is directly arranged in the shell without being connected with an external circuit board, thus the occupied space is greatly reduced; the inner side wall of the shell is provided with an annular groove (60); and the lower end of the switch rotor (3) is provided with a through hole (30), a compression spring (8) and a rolling ball (9), wherein the compression spring (8) and the rolling ball (9) are arranged in the through hole (30), and the rolling ball (9) is elastically compressed in the annular groove (60) under the action of the compression spring (8).

Description

technical field [0001] The invention relates to a rotary multi-position switch. Background technique [0002] A switch refers to an electronic component that can open a circuit, interrupt the current, or cause it to flow to other circuits. At present, mechanical switches on the market are divided into different operation modes: push type, trigger type, toggle type, rotary type, rotary The multi-position switch is widely used in electrical fields such as fans, lamps, radios, stereos, etc. due to its advantages of convenient use, multi-position adjustment, and reliable positioning. At present, a rotary multi-position switch has appeared, but this Domestic products of switches have poor positioning and power-on reliability, but to ensure the reliability of positioning and power-on, the volume of the switch must be made relatively large, so that the corresponding need to increase space accommodation and increase production costs, in some accommodation space It is inconvenient f...

[0002] A switch refers to an electronic component that can open a circuit, interrupt the current, or cause it to flow to other circuits. At present, mechanical switches on the market are divided into different operation modes: push type, trigger type, toggle type, rotary type, rotary The multi-position switch is widely used in electrical fields such as fans, lamps, radios, stereos, etc. due to its advantages of convenient use, multi-position adjustment, and reliable positioning. At present, a rotary multi-position switch has appeared, but this Domestic products of switches have poor positioning and power-on reliability, but to ensure the reliability of positioning and power-on, the volume of the switch must be made relatively large, so that the corresponding need to increase space accommodation and increase production costs, in some accommodation space It is inconvenient for limited equipment, such as gun sights and other equipment, and foreign products can find a similar function selection switch, which is imported from Europe. It needs to be connected with a self-designed circuit to achieve brightness and multi-function adjustment. The price is similar to domestic switches. More than 15 times, there are also the problems of complex structure and high cost. Moreover, the existing rotary multi-position switch does not have the limit function. Yes, the existing multi-position rotary switch generally adopts two ways to use at night: use fluorescent paint on the identification mark, or use LED lighting to facilitate and accurately find the gear. These two ways are easy to expose yourself. If this method is not adopted, the required gear cannot be found quickly and accurately, and there is also a certain inconvenience
