Automotive Intermittent Wiper DC Relay

Model: 3504A / 12-G, 3507A / 12-G, 3507A / 24-G

The windshield wiper offers revolutionized driving safety to automotive drivers, maintaining the visibility in rainy days. For wipers to be truly efficient to work in different driving conditions, an intermittent wiper relay is needed.

The intermittent DC relay is used for controlling the windshield wiper's operation. Working with automotive combined switch and windshield washing control switch, the relay controls the operation of the wiper motor.

Product information:

• Model:
  • HF3504A / 12-G
  • HF3507A / 12-G
  • HF3507A / 24-G
• Wiping time:
  • HF3504A (3504) / 12-G: 3.5s + 2.5s
  • HF3507A (3507) / 12-G: 3s + 3s
  • HF3507A (3507) / 24-G: 3s + 3s
• Intermittent time: 5.5s ± 1.5s
• Lifespan: 100,000 times
• Internal voltage drop: max. 150mV @ 5A
• Ambient temperature: -40°C - 85°C
• Net weight: 29g

Wiring instruction:

1. Terminal 15: power source positive (B+)
2. Terminal 31: power source negative (B-)
3. Terminals I & 53e (53M): combined switch K2
4. Terminal 31b (53S): wiper motor switch
5. Terminal 53c (T): washing pump switch

Intermit wiping: when the combined switch K2 is turned on (position 13), the terminal “I” is connected to B+ (12V or 24V), and the relay is started.

Washing wiping: when the switch K1 is turned on, the terminal 53c (T) is connected to B+ (12V or 24V), and the relay is started. When the switch K1 is turned off, after a delay (3.5s+2.5s or 3s+3s), the relay is stopped.
