Honeywell RDIHL Residential Door Interlock Switch

Honeywell’s RDI Series Residential Door Interlock switches are electromechanical devices designed for residential swing door applications, including elevators and dumbwaiters. These switches hold the door in place, preventing opening under unsafe conditions. Key features include a custom internal solenoid control to reduce controller complexity and power consumption, two Honeywell MICRO SWITCH switches for increased reliability, and a metal key for durability. The snap-action cam mechanism minimizes adjustment time and reduces nuisance shutdowns, while a Cat 5 connection option simplifies installation. The RDI Series is configurable and available in left- and right-hand versions, making it easy to retrofit into existing designs.
