The utility model discloses a miniature dialing switch with PCB, which includes a base and an upper cover. A PCB plate, a touch pad and a static touch piece are installed on the base. The PCB board is provided with a gold finger contact position and a common end contact strip, a slide opening is provided, a sliding seat is installed, a sliding block is provided on the top of the sliding seat, and a brush at the bottom of the sliding seat is provided. The electric brush is provided with a contact piece matching with the contact position of the gold finger, and a contact piece two matched with the common end contact strip. The advantages of the utility model in comparison with the existing technology are as follows: 1. The switch of the utility model uses the sliding of the metal piece and the PCB gold finger to change the gear position, and the change of the patch resistance or the change of the carbon film can be changed to change the gear position. The disadvantages of large volume and inconvenient installation are changed. 2, the utility model has the characteristics of small volume and multiple stalls, and can be made into a pole less switch according to the requirements of guests; and the structure of direct dial and circular dial can be selected by two structures. 3, the toggle block of the power switch is realized by closing and breaking the movable contact piece and the static contact piece to realize the ON/OFF function.
【技术实现步骤摘要】
一种带PCB微型拨动开关
本技术涉及开关,尤其涉及一种带PCB微型拨动开关。
技术介绍
传统的开关体积大,档位少,只有“直拨”设计,无“圆拨”设计,也没有无极档位调节设计,不便于安装。因此,研发一种体积小,档位多,既有“直拨”,又有“圆拨”,且有无极档位调节设计的带PCB微型拨动开关,成为本领域技术人员亟待解决的问题。
技术实现思路
本技术为了解决现有技术的上述不足,提供了一种带PCB微型拨动开关。本技术的上述目的通过以下的技术方案来实现:一种带PCB微型拨动开关,包括底座和上盖,所述底座上安装有PCB板、动触片和静触片,PCB板上设有金手指(碳膜)接触档位和公共端接触条;所述上盖设有滑动开口,并安装有滑座,滑座顶部设有拨动块,滑座底部设有电刷,电刷上设有与金手指接触档位配合的触片一,以及与公共端接触条配合的触片二。所述金手指接触档位为若干个档位触片。所述金手指接触档位为无极碳膜电阻触条。所述带PCB微型拨动开关的出线方式采用与PCB接驳的五金片在外焊线引出,或者,采用带扣线结构的穿线方式引出。本技术与现有技术相比的优点是:1、本技术的开关利用五金片与PCB金手指的滑动来改变档位,可以贴片电阻或碳膜的变化来改变档位。改变了之前体积大,不便于安装的缺点。2、本技术具有体积小,档位多的特点,还可以根据客人的要求无极档位;且具有直拨与圆拨两种结构可供选择。附图说明图1为本技术档位直拨式实施例的侧视结构图。图2为本技术档位直拨式实施例的俯视结构图。图3为本技术档位圆拨式实施例的侧视结构图图4为本技术档位圆拨式实施例的俯视结构图。图5为本技术无极直拨式实施例的侧视结构图。图 ...
