Features:
This product is a PWM-controlled relay switch, unlike FETs, it is a direct physical line connection, so it can be adapted to higher DC voltages and can also be connected to AC power
Small size and light weight
Solder two solder joints according to the markings in the diagram, then turn on the automatic disconnect mode
Recommend to find a professional to replace it, in case of damaging

Specifications:
Material: Metal
Length: 130mm
Quantity: 1 PCS

Console:
Input Voltage: 5V (connected to the receiver)
PWM Control: when high (>1750us), the normally open terminal and the common terminal are connected (while the normally closed terminal and the common terminal are disconnected)
(meaning that the normally closed and common terminals are connected at all times except when >1750us)
Here PWM is the servo signal, can turn the servo, you can use this device
There are solder joints can be set to delay 3 seconds, automatically disconnected

Connection Terminal:
30V DC, allowable current 2A
125V AC, allowable current 0.5A
Main Board Size: 29x9x8 mm
White Relay Size: 10x6.5x5.4 (mm)
Relay coil power consumption of about 140mW
The model should be used on the small relay

Package include:
1x Relay Switch
