  • The Intermatic KM2ST-2D In-Wall 24 Hour 20A SPST Mechanical Timer replaces a standard wall switch (toggle) to provide automatic control of outdoor or indoor lighting, fans, pumps, office machines, and other types of circuits. Captive trippers are easy to set and can not be lost. 72 trippers provide up to 36 ON/OFF events in a 24 hour period. A three way, OFF/AUTO/ON override switch provides continuous ON or OFF positions. The Mechanical Timer is easily wired and installed and is UL listed. A two-gang decorator-style wall plate is included. Single Pole, Single Throw (SPST) indicates the Timer can control one circuit (one set of lights, a spa pump, a fan, etc.) at the same time.

    Review of 48720 Review by MATTHEW
    Review of 48720

    I'm giving this a 4 out of 5 because it came with the wrong faceplate and there wasn't any mention of how to attach the control dial to the switch (that took a bit of trial and error to figure out).

    I ended up having to work with both SmartHome's and Intermatic's customer service people to get the correct faceplate and I'm happy to report that both companies were great to deal with.

    Outside of that, it's been installed for a month and it looks and works great. It was easy to install and program and I would not hesitate to buy another.
