How to switch between two Macs and one Thunderbolt Display?

I have 2 MacBook Pros and one Thunderbolt Display (27 inch). Both MBPs support Thunderbolt connectivity and work fine with external display. I need a way to switch between 2 MBP, without changing the connection everytime. Is there any hardware / KVM switch which supports this functionality? MBP Models are as below: * MacBook Pro (13-inch Mid 2012) * MacBook Pro (Retina, 15-inch, Late 2013)
