EECO's 1776 and 1976 thumbwheel switches are the
standards of the industry. Both series offer
8, 10, 12 or 16 position binary or
decimal codes for every possible
application
The 1776 are a standard .500" wide, while the
1976 are 350" wide to save valuable front
panel space. Optional notched terminals allow
motherboards to be easily attached.
The list of available options also includes
custom legends, lighting options, doublewide
units and fast mount installation hardware.
Many switch models offer diode provision or several optional P.C. board configurations, allowing the switch outputs to be bussed together. The 1776 and 1976 both offer proven reliability at a reasonable price, and are backed by EECO's
one year warranty.
