Main power switch assembly generally is installed in the battery compartment, connected to the battery positive terminal and eddy current retarder controller between. It is the main switch to control the eddy current retarder. When not in use for a long time, the main power switch of the eddy current retarder needs to be turned off.
The main function of the switching power supply is to cut high energy into countless low energies, and then transmit it to the output terminal, and the output terminal will also feedback the input terminal through the level of the output voltage. In this way, a stable output voltage can be achieved Effect.

The manual switch is divided into 5 gears, 0 means the retarder is closed, 1 means the retarder constant speed gear, 2 means 1/4 of the maximum retarding torque, 3 means 1/2 of the maximum retarding torque , 4th gear represents 3/4 of the maximum retarding torque, and 5th gear represents the maximum retarding torque.
The retarder handle switch is installed in the cockpit. The driver realizes the braking of the vehicle by selecting the appropriate gear. Typically mounted on the dashboard or under the steering wheel, it will provide one neutral gear and four to six control gears.

The control handle switch is installed at the lower right of the steering wheel, it is a multi-functional combination switch, the retarder can be controlled by pulling the retarder handle switch. Installed in the cockpit. The driver realizes the braking of the vehicle by selecting the appropriate gear. Typically mounted on the dashboard or under the steering wheel, it will provide one neutral gear and four to six control gears.

When the car is ignited, the retarder is in a standby state. When the car needs to be slowed down, the purpose of slowing down can be achieved by turning the handle of the manual switch to the required gear step by step. If you want to turn off the slowing down function, just use the handle Turn the control switch handle back to 0 gear.

The air pressure switch is a simple pressure control device. When the measured pressure reaches the rated value, the electronic pressure switch can send out a control signal. When the measured pressure exceeds the rated value, the free end of the elastic element produces a displacement to directly push the switch element, changing the on-off state of the switch element to achieve the purpose of control.
Mounted on the frame with the valve seat. It is connected with the front brake air path through the three-way and the air pipe, which is the control switch when the brake pedal is used to operate the retarder. Under the action of brake pressure, the pressure switch is switched on successively to control the action of the relay box.
