认识拨动开关

定义

• 拨动开关又称滑动开关是通过拨动开关柄使电路接通或断开，从而达到切换电路的目的.其按触点接触方式分为雪撬式、翘板式和弹片式-Three kinds of contact type of Slide Switch：sledge type,lever type and spring arm type
• 雪撬式拨动开关触点之间直接摩擦，寿命一般为10,000次以下，而弹片式、翘板式所过电流及寿命较雪撬式好
  Since the contacts of Sledge type switch are directly wiped each other, the life of
  Sledge type is relatively low (normally below 10,000 times）comparing with spring and lever type switch
• 可以有较多操作档位供选择-A variety of circuit options
• 可在两端档位做成回弹式功能-Momentary options

拨动开关结构

拨动开关分类

按照外型可分为基本型拨动开关、小型拨动开关；按照材质可分为塑胶外壳与金属外壳，按照电气性能可分为大电流拨动开关和小电流拨动开关等。

应用范围

拨动开关之应用非常广泛，常被用于家电产品、数码影音、电脑周边产品、通讯器材等行业

拨动开关使用注意事项

• 大规格（rating）的雪撬式拨动开关不能用在小电流（小于100毫安）的电路。
  Sledge type with high rating is not suitable for the current lower than 100mA.
• 弹片式的拨动开关不能用于较大震动的器具。
  Spring arm type is not suitable for vibration working area.
• 大规格(rating)的拨动开关不能用在小电流（小于100毫安）的电路，微小电流的触点应做特殊处理；如有类似的问题请我们联系。
  Generally, a high rating switch maybe not suitable for a rating less than 100mA of circuit. Some special designs of contacts are the solution of a low current rating．Please contact us for detail．
• 焊线或过波峰炉时必需注意温度及时间。焊线选用50-70瓦的恒温铬铁，上锡时间控制在3秒以内，过波峰炉时间控制在3-4秒，炉温控制在260度以下。The duration and temperature of welding and wave soldering are critical．Generally, the wattage of the temp iron is 50-70W, the duration of welding is with｝n 3 second，the duration of wave soldering is 3一4 second and the chamber temperature is below 260℃．
