1.1  Scope 范圍       This specification covers the requirements for single key switches which have no keytop

         (TACT SWITCHES:MECHANICAL CONTACT ). 此規(guī)范含蓋單推柄和無(wú)推柄的輕觸開(kāi)關(guān)要求。

1.2  Operating Temperature Range  使用溫度范圍

         -20 to 70 ℃(normal humidity, normal press).正常濕度，標(biāo)準(zhǔn)壓力

1.3  Storage Temperature Rang    保存溫度范圍

         -20 to 80 ℃(normal humidity, normal press).

1.4  Test Conditions    測(cè)試條件

         Tests and measurements shall be made in the following standard clnditions unless otherwise specified:

         測(cè)試和計(jì)量按下列標(biāo)準(zhǔn)條件除非特殊說(shuō)明

         Normal temperature (temperature 5 to 35℃)      標(biāo)準(zhǔn)溫度

         Normal humidity (relative humidity 45 to 85%)    正常濕氣

         Normal pressure (pressure860 to 1060 mbars )     標(biāo)準(zhǔn)壓力

         In case any question arises from the judgement made, tests shall be conducted in the following conditions：

         Temperature               (20±2℃)           溫度

         Relative humidity           (65±5%)           相對(duì)濕度
