An entry for each switch in the monitored system. Switches report true/false status and are useful for indicating open doors, unlocked keys, etc. There may be zero or more rows in this table. One column, uemSwitchContext, is a displayable string that reports the meaning of the current true/false state of the switch such as 'Open', 'Closed', 'Locked', 'Unlocked' etc. Other columns allow access to the actual true/false state and which state is expected in a properly operating system.
