An Alto Shaam SW-3905 Boot shields the switch area from moisture and debris for dependable control.
The boot covers and protects the switch area while allowing reliable actuation of the control in heated merchandisers, display cabinets and heated shelves. Its silicone rubber construction matters because it withstands heat, moisture and repeated use while maintaining a flexible seal that supports consistent switch performance.
The boot may need to be replaced if the switch becomes harder to press, feels less responsive or can allow inconsistent control operation during equipment use. Physical signs can include cracking, tearing, brittleness or warping and environmental signs may include heat-related degradation, moisture intrusion or residue buildup around the switch opening.
