Sure, there are several devices of this type, although some look much more like buttons than regular switches.
Zwave or Zigbee devices that communicate to the SmartThings hub.
These are the easiest to use with smartthings, although they will require that the hub be operating in order for them to function. There are at least a half a dozen of these, maybe more. Again, some look just like a wall switch, some look like a button.
For example, although the ecolink toggle is designed to fit over an existing dumb switch, it can be installed without one.
The Eaton Cooper Anyplace Switch is zwave and is designed to look exactly like their regular switches. It comes in several different styles and colors.
Or there are some zigbee button devices like the one @Automated_House mentioned.
You can find all of these and more listed in the buttons FAQ. The FAQ includes both mains powered and battery powered devices, so read the descriptions carefully.
In most cases, the post will include a link to a discussion thread about that particular device.
The FAQ is only intended to have one or two posts per device. So if you have any questions about devices which are listed there, please do not add them to the FAQ or it getS too cluttered. Instead, either go to the discussion thread which is linked for that device, or come back here and ask your question. Thanks!
