As others have said, the push button switches on the Tirgress
Windlass are not standard, but are added by Amel.
The rubber covers and the switch assemblies are available from
Amel at a modest price. They are easily replaced. Since shipping
costs are the major portion of almost any bill from Amel I chose
to get 4 switches and 6 rubber covers when I ordered.
The rubber covers have lasted about 4 years in the Caribbean
Best of luck.
