Need a part number for the Kenwood TM-741A/E
 

Hi folks,
I need the part number of this component on a Kenwood TM-741A/E
transceiver:

push-botton switch S5 (MHz switch), located on the Display Unit.

I have the schematic diagram, but parts numbers are not listed on it.
I need this number to order this part From Kenwood (by the way, it
could be ordered from Kenwood directly on: www.kenwoodparts.com).

Many Thanks, 73s
