The invention relates to an isolation switch having a contact indication function, which mainly solves the problems that a transparent cover is easy to be blackened by an arc during product disconnection and the status of a contact cannot be clearly viewed due to no contact connection/disconnection indication during switching on or switching off of a conventional isolation switch and the transparent cover is only adopted as a visual contact. In the isolation switch having the contact indication function, provided by the invention, an indication element is arranged on a shell and is movably matched, the indication element exceeds the surface of the shell under the ejection of a movable contact during switching off and drops below the surface of the shell during switching on, the status of the contact can be clearly displayed, and the isolation switch is more convenient to use.
