Operators Manual

Page 37

Note that either individual momentary action or latching switches may be used.

Additionally, a rotary switch may be used, but realise that this will mean that the
seven memories will only be accessible in a linear fashion. Individual switches allows

“Random Access” of the memories in any order which might be more useful. The

type of switch used to build a remote interface is not crucial, but XTA suggest the
following as suitable.

Farnell Components Order Code 176-477 (Momentary Push-button Variety)

Farnell Components Order Code 176-478 (Latching Push-button Variety)
Farnell Components Order Code 176-487 (Mounting Bracket for Interlocking Set)

Farnell Components Order Code 176-516 (Interlocking Cam)

Farnell Components Order Code 176-491 (Round Caps)
Farnell Components Order Code 176-492 (Rectangular Caps)

For a rotary switch we suggest:
Farnell Components Order Code 422-381 (Rotary Non-Shorting)

Note that the rotary switch must be a ‘break before make’ variety, or unpredictable

operation may occur.
