Hi-ox240a is the unidirectional machine-room-less speed governor.
If the elevator descends with excessive speed, the descending brake will be used to support the general descending safety gear, enable the safety gear, and stop the car, playing the role of descending over-speed protection.

If the elevator ascends with excessive speed, the over-speed switch can be turned off to cut off the power and stop the car, playing the role of ascending over-speed protection.
The electromagnet switch can be used to detect the actuation of the speed governor, and detect the elevator.
The remote control is available.
