Dual Surface-Mount On/Off Switch · 120/277 VAC 20A per switch · Weatherproof box · Infratech 14-4425
What this product is for
This is a dual surface-mount on/off switch assembly with a weatherproof box for controlling compatible Infratech radiant heaters in outdoor or exposed locations. It provides two independent on/off switches in one assembly where in-wall mounting is not practical.
Use for
Use for outdoor patio heater control points, covered commercial patios, restaurant terraces, residential outdoor living areas, and other installations using compatible Infratech C-Series, SL-Series, or W-Series heaters. It is suited to surface-mounted installations where weather protection for the switch assembly is required.
Avoid for
Avoid using this as a dimmer or variable heat control, or where a flush in-wall control is required. Do not use beyond the stated electrical rating, and do not assume one switch can control more load than the manufacturer allows.
Best for
Best for electricians and contractors needing a straightforward outdoor heater control with independent switching in a single weatherproof assembly. It is a practical choice when wall construction, retrofit conditions, or exterior finishes make recessed mounting difficult.
Installed in
Typically installed on exterior walls, posts, service areas, and outdoor living spaces. Approximate overall size is 5.5 in. x 3.63 in. x 2.25 in. (140 x 92 x 57 mm), which helps when planning surface clearances and conduit entry.
Why this product exists
This control assembly exists to provide simple, separate on/off control for two heater circuits or elements in a weather-protected surface-mount format. For many outdoor heater layouts, a basic switch assembly is the most direct control method and can simplify operation and service access.
Compared with similar products
Compared with flush-mount switch kits, this model is intended for surface installation and includes a weatherproof box for exposed locations. Compared with timer or dimmer-based controls, it offers basic on/off operation only. As a typical rule of thumb, simple on/off controls are commonly selected where staged heat control is not required and straightforward switching is preferred. Actual control suitability depends on heater configuration, circuit design, and local electrical code.
