Direct current and alternating current contactor for remote telephone control system, has retaining coil connected to micro switch contact, that replaces magnetic coil to attract movable iron core, when magnetic coil is disconnected
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.
