relay contact的用法和樣例：
例句
- Relay contacts should be shielded from the coil to minimize induced noise from the relay power supply.
繼電器觸點和線圈之間應該屏蔽，以使繼電器電源引起的感應雜訊最小。 - Most switch mainframes can be triggered externally via the trigger input and can send an output trigger pulse when the relay contacts have settled.
大多數開關主機都可通過觸發輸入進行外部觸發，並且在繼電器觸點穩定之後可輸出一個觸發脈衝。
