保持式电磁铁 Keep solenoid
产品特征:此款电磁铁自带永磁铁，未通电时，顶杆保持释放状态，通电时顶杆吸合，断电后，顶杆保持为吸合状态，给相应的反向电压，顶杆由吸合状态复位成释放状态，断电后，顶杆保持释放状态。
Features
Permanent magnet used for keep solenoid. When unpowered, plunger keeps in the release
status; and when energized, the plunger pulls in, and then powered off, still in actuation. If given
the corresponding reverse voltage, the top bar resets from pull-in to release status, and maintain
in release status after outage.
应用范围 Application Area
汽车大灯，咖啡机，汽车充电桩等。
Automotive headlights, xenon headlights, coffee machine, trickle charge for vehicles etc.

推拉式电磁铁 Push-pull solenoid
产品特征：通电后动铁芯推出或拉回，推动负载，断电后动铁芯靠弹簧复位。
Feature:
When energized, movable iron core is pushed out or pulled in, pushing the workpiece. After outage, the iron core is reset by spring.
