Click to enlarge
The switch module is commonly used to monitor whether a door is open or closed. In normal use a (supplied) magnet is attached to the door to be monitored and the EL029 to the door frame. Alternatively an external microswitch (not supplied) can be wired in. The display on the logger reports either 'Open' or 'Closed'.
