CONTROL SWITCHING
Control Switching Using DPDT Switches
This information describes how to achieve dual switching with one magnetic
contact and one magnet. DPDT magnetic contacts such as the Sentrol 1087D,
1084D, 2507AD, or 2707AD (see catalog) may be used in place of two contacts or
one contact and a floor mat for an annunciator panel. Other applications include
access control multiplex systems, computer monitoring of doors, lighting control
and safety systems. DPDT switches are available in recessed, steel door, surface
and industrial outdoor models.
Note: Each switch is electrically and mechanically isolated from the other and
may switch at a slightly different point.
