The 7-segment digits will not handle switches

Perhaps this may be useful to you

multiplex 5 digits
01/01/70 00:00
Don't think anyone would want 1:35 degenerate "multiplexing"
01/01/70 00:00
Have I done the sums wrong?
01/01/70 00:00
No but multiplexing requires few driver lines
01/01/70 00:00
You MUST have digit drvers
01/01/70 00:00
You missed '4094 OE+PWM for luminocity
01/01/70 00:00
No multiplexing needed...
