Common Concerns Answered
What if I have more than two AC power sources to select from?
This Newmar SS Switch offers 2 selection positions plus OFF, ideal for standard shore power and generator setups. For systems with three or more primary AC sources (e.g., including an inverter as a primary source), consider multi-position switches or additional switching logic to manage your power distribution safely.
Is this switch significantly more expensive than basic alternatives?
The price reflects its robust construction, critical safety functions, and industry certifications (cUL, CE), which are paramount in marine electrical systems. Investing in a certified, reliable switch prevents costly damage and potential hazards compared to non-certified, lower-cost alternatives.
Are replacement parts readily available for older Newmar selector switches?
Newmar products are built for durability; however, specific replacement parts for older models can occasionally present sourcing challenges. The SS SWITCH3 is a current production model, ensuring parts availability for this specific unit.
