Noise-free low-power consumption wide voltage range dc and ac contactor

摘要

The contactor has movable iron core and micro switch connected to opposing ends of linkage. The micro switch has normally closed contact connected in series to magnetic coil and in parallel to integrated circuit (IC) and retaining coil. The contactor conducts when magnetic coil attracts iron core to move downwards. The retaining coil replaces magnetic coil to attract the iron core, when magnetic coil is disconnected.
