Toggle on/off. Multiple levels, nearly immediate on well before any engine source can deliver. And no noise. With an inline fuse, no need for a circuit breaker. My copilot always loves the near instant on seat heat during early start up and taxi. Can even preheat off the secondary buss prior to engine start.
