This product is PWM controlled relay switch, different from the field effect tube, it is directly established the physical line connection, so can adapt to higher voltage, but also can connect to AC.

Features:
response speed allows for quick switch operations, improving the efficiency of the device. 
The PWM-controlled relay switch has durability and stability, reducing the occurrence of faults and lowering maintenance costs. 
The design is simple, making installation and use very convenient. 
The PWM relay switch can be used in conjunction with various types of models and remote controls. 
The working method of the PWM PWM on-off relay switch can short circuits or fires caused by excessive current, enhancing the safety of use.

Specifications:
Item Name: PWM Controlled Relay Switch
Main Material: Metal
Control Terminal:
Input voltage: 5V (connected to the receiver)
PWM control: at high (>1750us), NO(Normal Open) and COM(Common) are connected (at the same , NC(Normal Close) and COM(Common) are disconnected).
(This means that NC (Normal Close) and COM(Common) are connected at all times except >1750us)
Here PWM is the steering gear signal, can turn the steering gear, and you can use this device
There are solder joints that can be set to delay 3 seconds, automatic disconnect
Connecting End
