Delta offers a variety of specialty switches that can be customized to fit your individual wiring harness needs. Put through a series of rigorous tests, our lanyard, dome and flame retardant switches will survive in the most rugged environments.
The lanyard switches and dome switches are sealed and have proven reliability in wet environments. They are used in applications like marine engines, boats, go-carts, exercise equipment and off-road vehicles. Designed with twin O-rings on the plunger shaft and complete encapsulation at the wire lead exits, Delta’s lanyard switches withstand water submersion to depths of 10 feet. They offer a variety of mounting configurations, brackets and terminations, which allow for placement flexibility. They can be mounted on or below control panels or on engines or chassis. The single-pole, single-throw circuitry is available in normally open or normally closed configurations. Delta's flame retardant switches are UL certified for electric, battery-powered industrial trucks. lnternal contacts are self-cleaning to prevent carbon build-up and increase life.
