Price Excluding VAT: 399 kr
Discover the perfect solutions for your electrical projects with our 5-pole waterproof relays! These high-quality relays are designed to handle currents up to 40A and work on both 12V and 24V DC. With their rugged construction and reliable performance, these relays are ideal for automotive and marine projects, fan control and more.
The relays are excellent for use in polarity switch applications, where you need to reverse the current flow to control actuators, trim plane pistons or DC motors. They have been proven in electric trim piston racing and have proven to be both reliable and durable.
The relays are easy to replace if they should break and are quickly mounted with the supplied bracket. The bracket has a mounting dimension of 131mm (CC) between the screw holes and uses M6 mounting holes , making installation smooth and safe. In addition, the entire package weighs only 300g, including both relay and bracket, making them easy to handle and install in various projects.
Wiring diagram and Connection details (suggestions):
To create a polarity switch circuit to control a DC motor or actuator, connect the relays as follows:
- 87A and 85 : GND (12V-)
- 87 : 12V+ (power to the engine or system)
- 30 : Connects to the actuator or electric motor input
- 86 : Connects to switch to activate the relays
This coupling allows you to easily switch between forward and reverse movement of a motor or control of the actuator by reversing the polarity.

Wiring diagram for Polarity switch:
To assist you with installation, below is a recommended wiring diagram where two relays are used to control the polarity of a DC motor or actuator. This enables easy control of the motors direction (forward/backward) depending on the clutch. The positive base of the switch and connection to the relays are also shown in the diagram for clearer installation.
