To switch into frame in selenium use swithTo() and frame()method.
driver.switchTo().frame(iframe_Login1); driver.switchTo().frame(iframe_Login2); driver.switchTo().frame(iframe_Login3);
To switch back we can use parentFrame() and defaultContest();
parentFrame() : Change focus to the parent context. If the current context is the top level browsing context, the context remains unchanged.
driver.switchTo().parentFrame();
defaultContent() : Selects either the first frame on the page, or the main document when a page contains iframes.
driver.switchTo().defaultContent();
