-    * In switch mode, the relay will be switched to control an appliance like a radio or light fixture. If used with timer, it will switch on while timer is running (like a "sleep" function). If used with alarm, it will switch on when alarm trips; specify **alarm switch duration** (default 2 hours). Also specify:
-      * **whether soft alarm switch** is enabled. Default is yes; it is switched with Adjust while viewing the alarm time. Change to no if the appliance has its own alarm switch; the clock's alarm will be permanently on.
-      * **whether soft power switch** is enabled. Default is yes; appliance can be switched manually with Adujust while viewing the time of day. Change to no if the appliance has an independent power switch or does not need to be manually switched.

 **To compile the edited sketch:** You will need to add the [ooPinChangeInt](https://code.google.com/archive/p/oopinchangeint/downloads) and [NorthernWidget DS3231](https://github.com/NorthernWidget/DS3231) libraries to your Arduino IDE.
