|Maksim Salash continues to shine for Belarus, who are still unbeaten in Sarajevo|
The Dutch went into the game having split their opening two contests while Switzerland were winless through three.
And the game seemed to be following form as the Netherlands held a 47-39 advantage entering the final period.
But they added just five points to their total as they faltered from the floor - and the free throw line - and Switzerland set up a grand finale when Branislav Kostic followed Arnaud Cotture's fast-break dunk with a three-pointer which made it 50-49.
But Shane Hammink extended the lead to 52-49 from the free-throw line before Cotture missed the shot to tie at the buzzer.
Ukraine continue to set the pace in Group A however after they improved to 3-1 following a comfortable 79-59 success against Finland.
Vladyslav Koreniuk was the standout performer for Ukraine once more as he scored a game-high 24 points and reeled in ten rebounds. Niko Mattila was in good form for Finland too, finishing with 20 points, but his team just couldn't keep with Ukraine and slipped further and further behind as the game progressed.
Belarus remain in hot pursuit of Ukraine, perfect through three games, after they saw off the challenge of Georgia 82-63 off-the-back of an 18-0 second-quarter spurt.
The hosts, Bosnia and Herzegovina, are also unbeaten at 4-0 with their latest success a 95-57 rout of Estonia, in which they led from start to finish.
Bosnia and Herzegovina were a class apart in all categories, so much so that five of their players registered double figures in scoring and they will be confident ahead of their meeting with the group's other unbeaten team, Portugal on Tuesday.
Romania are right behind Portugal and the hosts at 2-2 as they held off a late Luxembourg rally on Monday, 79-68.
Romania led by 17 heading into the final ten minutes but were required to close with six unanswered points as Luxembourg began to eat in the deficit with improved shooting late on.
The other game in Group A saw Belgium improve to 2-1 by virtue of a wire-to-wire 58-41 victory over Cyprus, led once again by the scoring of Emmanuel Lecomte, who this time finished with 15 points.
