Product Use

This 12 VDC Relay is especially developed for Automotive use as servo change over switch.

Low current (Typically 140 to 150 milliAmperes) through the Relay Coil electromechanically switches ON a High current Load (up to 40A).

In constant ON applications it can carry up to 40 Amperes, while in pulsed applications up to 30 Amperes may be switched momentarily.

Millions of these devices have been reliably used since 1987 in following applications:

• Air Horn Servo
• Headlight Control
• Fog light Control
• Driving light Control
• Intermittent Wiper Control
• Ventilation Fan Control
• Radiator Fan Control

Features

• Single Pole, Double Throw (On/Off, Off/On)
• Mounting Bracket
• Nominal Voltage 12V
• Operating / Releasing Time ≤ 10 ms / ≤ 5 ms
• 10,000,000 Mechanical Cycles Life
• Coil Resistance 85 Ohm ± 10%
