Switzerland is also a rarity where there isn’t quite a separate head of state (eg UK Monarch, German President) but also the head of government role is done by a council of seven, where the majority decision is what happens. So the legislative body writes the law and the council of seven is tasked with executive power to carry out the law.

The modern Swiss constitution (1848) took inspiration from the American constitution (1789), but rather than a consolidated head of state/government like the American President, they wanted to hew even closer to the long-standing ideals of democracy amongst the Cantons, to also avoid concentrating too much power to individuals. Thus, even though the Swiss Federal Council rotates the title of president every year in turn, it confers zero extra powers.
