Restore automatic step extension and retraction to your Kwikee electric step system with this OEM-style large round door jam switch. Mounts directly in the RV entry door frame and signals the step controller every time the door opens or closes -- no more steps that stay out when the door is shut, or fail to deploy when you open up.
Kwikee electric step systems rely on a door jam switch to know when the entry door has opened or closed. When that switch fails -- corroded contacts, broken plunger, or damaged wiring -- your steps lose their automatic trigger. The result is either steps that never extend when you open the door, or steps that stay deployed when you close up and drive away.
The Lippert 378054 (vendor part 97-2780, UPC 848150025845) is the large round format of this switch, designed as a direct service replacement for compatible Kwikee step installations. It installs in the door frame and actuates mechanically as the door moves, sending the signal to the step controller to extend or retract the steps.
Engineered to match original Kwikee step switch mounting and wiring specs for a direct swap with no fabrication.
The larger round housing suits door frames with wider switch cutouts -- verify your existing switch profile before ordering.
Includes the switch sensor, two pre-attached lead wires, and a hinge-style mount bracket for straightforward installation.
Matte black housing blends with standard RV door frame trim and matches typical factory Kwikee switch appearance.
Hardware for mounting to the door frame is typically sourced on-site to match your specific door frame material and thickness.
The switch body mounts in the entry door frame. When the door closes, it depresses the switch plunger, signaling the Kwikee step controller to retract the steps. When the door opens, the plunger releases and the controller extends the steps (depending on system configuration and the ignition interlock setting). Proper plunger engagement depth is key -- the switch must be positioned so the door makes clean, full contact with the plunger every time it closes.
