Common Concerns Answered
Will this switch work like my old ON/OFF switch?
The Blue Sea 7930 features an OFF-(ON) momentary action, meaning the circuit is only active while you are pressing the button. If you require a switch that stays in the ON position after being activated, you would need a latching ON-OFF switch.
Can I mount this switch anywhere on my boat?
While the switch itself is designed for harsh marine environments, optimal panel mounting and water resistance are best achieved when used with Blue Sea Systems' Contura Water Resistant Panels or Contura Switch Mounting Panels.
Is this switch too expensive for my needs?
The Blue Sea 7930 represents an investment in reliability and longevity for critical boat systems, offering superior durability and environmental sealing compared to less expensive alternatives. Consider the cost of potential failure with a less robust switch in harsh marine conditions.
