Overview
Harken Digital System Switches set the standard for the reliable operation of electrically-powered yacht systems. To accomplish this, safeguards have been built into the systems. • The waterproof control button translates electrical information into a binary code that won’t allow the system to start without the signals being verified by the decoder. An analog system sends continuous electrical information directly to the powered device which means damage to the wiring or water ingress could result in unsafe activation. • Watertight seals are never exposed, eliminating potential damage from sun and prolonged use. • Underneath each control button, two command switches must work in unison before a signal is sent.
Harken Digital System Switches resist impact, wear, and abrasion. A unique adhesive mounting system is available where drilling is undesirable. The product is offered in black polyamide resin or stainless steel. Integrated lighting provides low-light visibility. Two-function control buttons housed in a single space-saving system—1st/2nd gear for winches, up/down for anchors, in/out for furling.

FAQs
The switch uses an adhesive base for deck installation; drilling is only required for wiring.
Before use, check correct wiring; if functions are swapped on dual switch, invert grey and brown wire connections.
Wait for 72 hours after installation before applying any stress to the switch.
Carefully clean and degrease the installation surface with isopropyl alcohol before mounting.
No maintenance operations are necessary under normal use for this device.
The installation surface should exceed 10 °C (50 °F) for proper adhesive bonding.
Carefully clean and degrease the installation surface with isopropyl alcohol and let it dry completely (about 2-3 min).
If installing on teak, avoid crossing planks; drill all holes on a single wood plank.
Follow the wire color code and, if activation is incorrect, invert the grey and brown wires when testing.
Connect by coupling the connectors of the button and Control Box; do not connect the Decoder.
