DESCRIPTION

The 82-650-10 is a lightable gray modular keyboard module featuring 6 buttons with SPST (Single Pole Single Throw) circuitry and support for insertable legend inserts. The module maintains a standard button center spacing of 11/16" and is designed to stack with other modules in any configuration while preserving consistent button distances. It accommodates T-1 incandescent lamps with a maximum allowable ambient temperature of 130°F for standard plastics and 200°F for special plastics, with lamp options providing either bright (0.15 MSCP at 5V, 115 mA) or moderate (0.03 MSCP at 5V, 60 mA) illumination. The keyboard features wiping contacts with a contact resistance of 25 milliohms or less, an insulation resistance of 1,000 megaohms minimum, and a rated life expectancy of 1,000,000 operations. This module is ideal for applications requiring custom-labeled illuminated control panels, instrumentation interfaces, and industrial equipment where professional appearance and durability are essential.
