Formulate the part number with the exception of the legend suffix. 2.Mounting. Standard mounting is shown in our dimensional drawings. These drawings relate the terminal location to the button legend orientation. It is possible to rotate the button legends by 90, changing the orientation. When mounting the keypad, it would be rotated 90 to have the legends appear upright. A 3x4 keypad thus becomes a 4x3. 3.Color. Many colors, other than our standard black housing, are available. Buttons can be made from equivalent plastic in black, red, green, blue and yellow.White legends are used with dark color buttons, black with light ones. Other colors available on special order. Part Number Available from your local Grayhill Distributor. For prices and discounts, contact a local Sales Office, an authorized local Distributor or Grayhill. 4.Buttons. Legends can be printed on button surface and protected by a snap-on cap in a similar fashion to our insertable legend types. A second option is printing a `blank' button. (One that has the same dimensions as a molded-in legend button with a flat top surface.) Disadvantage is legend wear over time. A third option is molded-in legends, usually requiring tooling. Molded buttons are available with a flat or concave top surface. 5.Legends. Specify the legend requirements for each button. Identify buttons per our dimensional drawings. Caution if keypad has been rotated.
