Yes, except that the "votations" happen 4x per year. Here are all the next ones: https://www.bk.admin.ch/ch/f/pore/va/vab_1_3_3_1.html

Each will have 1-4 issues (approx) scheduled. Elections for politicians happen every 5 years, but no need to wait for those. What takes time (for votations) is the process: you have to verify the signatures once they're handed in at the federal chancellery and then decide when to schedule it.
