Mini Model RC Car Boat Remote PWM Relay Switch Remote Control Universal Switch Specifications: Material: Metal Size: As shown in the pictures Console Input Voltage: 5V (connected to the receiver) 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: Approximately 140mW Weight: 3.3g Features: PWMControlled Relay Switch: This switch is not like FETs but a direct physical line connection, allowing for higher DC voltages and AC power connections. Compact and Lightweight: This smallsized relay switch doesn't add unnecessary weight to your model car or boat. Automatic Disconnect Mode: Solder two joints according to the diagram markings to activate the automatic disconnect mode. 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) Delay Feature: With solder joints, you can set a 3second delay for automatic disconnection. Package Included: 1x PWM Relay Switch
