Output Codes/Terminals
• Switches with output codes 06 or 07 both
• How to Read Output Codes
20.5
use binary coded decimal but Switches
with output code 07 have a component-
adding provision. Similarly, Switches
with output codes 54 or 55 both use
binary coded hexadecimal but Switches
with output code 55 have a component-
adding provision.
For example, when the dial position is
“3,” the common terminal C on the
Switch is connected to terminals 1 and 2.
When the Switch is inserted into the
Connector, the common terminal C
becomes connector terminal 3, and
terminals 1 and 2 become connector
terminals 5 and 7 respectively.
