Item項目 | Test Condition試驗條件 | Requirements規格 |
6.2.1. Actuating Force 動作力 | Placing the switch such that the direction of switch operation is vertical and then gradually increasing the load applied to the center of the stem, the maximum load required for the stem to come to a stop shall be measured. 開關的動作方向為垂直放置開關向推柄中心逐漸增加負荷直到推柄停止時所測量的最大負荷 | _____±30 gf |
6.2.2. Travel 行程 | Placing the switch such that the direction of switch operation is vertical and then applying a static load twice the actuation force to the center of the stem, the travel distance for the stem to come to a stop shall be measured. 開關的動作方向為垂直放置開關，在已有行程的推柄中心向上減小壓力，推柄回到自由位置時所測到的力 | 0.3±0 .1mm |
6.2.3. Return Force 返回力 | The sample switch is installed such that the direction of switch operation is vertical and, upon depression of the stem in its center the whole travel distance ,the force of the stem to return to its free position shall be measured. 開關的動作方向垂直放置開關，在已有行程的推柄中心向上減小壓力，推柄回到自由位置時所測量到的力 | ____±20 gf min |
6.2.4. Stop Strength 靜止強度 | Placing the switch such that the direction of switch operation is vertical, a static load of3 kgf shall be applied in the direction of stem operation for a period of 60 seconds. 開關的動作方向為垂直放置開關，在推柄動作方向施加3 KG的靜負荷，60秒時間 | There shall be no sign of damage mechanically and electrically 無機械的和電氣的損傷跡象 |
6.2.5. Stem Strength 推柄的強度 | Placing the switch such that the direction of switch operation is vertical, the maximum force to withstand a pull applied oppsite to the direction of stem operation shall be measured. 開關的動作方向為垂直放置開關從推柄動作方向反方向施加拉力所測量到的最大承受力 | 3 kgf |
使用開關時註意事項
1.IN CASE AN AUTOMATIC FLOW SOLDERING APPARATUS IS USE FOR SOLDERING
用自動焊接設備焊接時應參照如下條件
ITEM項 目 | SOLDERING CONDITIONS焊接條件 |
(1)PREHEAT TEMPERATURE預熱溫度 | 100℃ MAX(AMBIENT TEMPERATURE OF PRINTED CIRCUIT BOARD ON ITS SOLDERING SIDE)(電路板周圍焊錫麵的溫度) |
(2)PREHEAT TIME預熱時間 | 45 SEC MAX45秒MAX |
(3)FLUX FOAMING助焊劑浸泡 | TO SUCH AN EXTENT THAT FLUX WILL BE KEPT FLUSH WITH THE PRINTED CIRCUIT BOARDS,TOP SURFACE ON WHICH COMPonENTS ARE MOUNTED.PRDPARATORY FLUX MUST NOT BE APPLIED TO THAT SODE OF PRINTED CIRCUIT BOARD ON WHICH COMPonENTS ARE MOUNTED AND TO THE AREA WHIERE TERMINALS ARE LOCATED.助焊劑應塗在電路板上組裝開關的印刷麵上半部位，應防止助焊劑過量到電路板. |
(4)SOLDERINTEMPERATURE 焊錫溫度 | 255℃ MAX255℃ MAX
|
(5)DURATION OF SOLDER IMMERSION焊接時間 | 5 SEC MAX5秒 MAX |
(6)ALLOWABLEPREQUENCY 允許重焊次數 | 2 TIMES MAX2次 MAX |
2.OTHER PRECAUTIONS其他註意事項
(1) FOLLOWING THE SOLDERING PROCESS,DO NOT TRY TO CLEAN THE SWITCH SOLVENT OR THE LIKE
進行焊接工藝時不應使用不整潔的東西對開關進行清潔。
(2) SAFEGUARD THE SWITCH ASSEMBLY AGAINST FLUX PENETRA TION FROM ITS TOP SIDE
在組裝開關時應防止助焊劑從開關的上部流入到開關內部
