Key Features:

  • SPDT (Single Pole Double Throw) configuration for dual circuit control
  • (On)-Off-On momentary operation with spring return from first position
  • Water-resistant design rated for harsh marine environments
  • Resistant to vibration, shock, thermal shock, moisture, and salt spray
  • Black actuator with integrated LED indicator capability
  • Designed for mounting in Blue Sea Systems Contura panels
  • Compatible with both Contura Water Resistant Panels and standard Contura Switch Mounting Panels

Ideal for applications requiring momentary activation in one direction and maintained connection in the other, such as windlass control, trim tab operation, or spotlight positioning. Built to withstand the demanding conditions of marine and mobile environments.

Very fast shipping plus I saved a ton of money on the same lift kit I would have purchased locally!

I hope this fits.

Great products, Fast Shipping, Good Price!

I ordered the Keep Toolbox Jerry can, what a great piece. Construction is pretty good for not being made in the US but it is rather heavy compared to real Jerry cans. Definitely a great piece!<br>-J Tuttle
