Digital System Switches
Harken Digital System Switches in dual and single-function models 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.
