Wall Plate Shield Sealing for Liquid-Resistant Indoor Switches
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wall switch devices are vulnerable to liquid ingress and contamination due to gaps between wall plates and switches, which can detrimentally impact their operation.
Innovation Solution
A wall plate system with a shield that extends through the aperture and forms a seal between the wall plate and the electrical device, using a flexible material like silicone to cover and protect the electrical device from liquids and contaminants while allowing sensor components to function normally.

If a rigid shield is used to seal the gap, then liquid ingress is prevented, but sensor components cannot function normally due to blocking
Solution Approach 1:
The flexible shield material allows for precise shaping and cutting to create openings or windows in strategic locations. These openings permit sensor components (such as optical sensors or touch sensors) to remain exposed and functional while the surrounding flexible material maintains the liquid seal around the wall switch device.
Solution Approach 2:
The shield is designed with non-uniform properties: solid opaque material in areas requiring liquid sealing, and transparent or open areas in locations where sensor functionality is required. This localized differentiation allows the same component to simultaneously prevent liquid ingress and maintain sensor operation.

AI summary
A wall plate system for an electrical device, including but not limited to indoor wall switches, includes a wall plate and a shield. The wall plate defines an aperture, and the wall plate is configured to receive a portion of an electrical device in the aperture. The shield extends at least partially through the aperture, and the shield is configured to form a seal between the wall plate and the electrical device.
