With ballot-counting still underway, the exit polls suggested that the proposal -- put forth by far-right politicians -- enjoyed around 59 percent support.
Prior to the referendum, opinion polls indicated that more Swiss would oppose rather than support the ban.
Earliest results after polls closed at mid-day (1100 GMT) showed that at least four cantons -- all in German-speaking Switzerland -- want a ban on minarets.
Partial results also showed that Lucerne is for the ban, while French-speaking cantons Geneva and Vaud are against.
The Swiss People's Party (SVP) -- Switzerland's biggest party -- had forced a referendum under Swiss regulations on the issue after collecting 100,000 signatures within 18 months from eligible voters.
It claims that minarets -- the turrets or towers attached to mosques from where Muslims are called to prayer -- symbolise a "political-religious claim to power."
The Swiss government has asked voters to reject the call, arguing that accepting a ban would bring about "incomprehension overseas and harm Switzerland's image."
