The Schwank On-Off Control Switch is specifically engineered for use with eSchwank ES and ESD electric heaters. It allows operation of a single or dual electric heater with a simple flip and is suitable for both indoor and covered outdoor spaces. Choose between flush in-wall or surface mount styles to suit installation needs; each electric heater should have a dedicated switch for safety and reliability. For larger areas or multiple electric units, additional switches provide complete control for each installation.
In uncovered or fully exposed outdoor areas, selecting a weatherproof switch cover is required. This weatherproof cover is built for electric installations, guarding the switch and its electronics against rain, snow, and other harsh conditions, ensuring lasting safety and function. The weatherproof switch option is certified for electric heater use in open, fully exposed locations. All models feature a durable stainless steel face plate, providing corrosion resistance and long-lasting protection for the electric heater’s controls.
