Rainbow D4C Main Power Switch
Kit 6 Hole Version 6 Hole Version

This switch works with all D4C and SE Rainbow systems. If you have a switch with 6 holes where the wires push in, please read the information below on how to wire this version.

Factory OEM switch for the D4C SE (Special Edition) and D4C model Rainbow. This switch first came as pictured (diagram) in the early version D4C that came out in 1986. Rexair then changed to a new design switch that did not have wires attached. The new version had six holes that you would stick the wires into. Inside each hole was a spring-loaded catch that held the wires in place.

Over time, the factory found this inferior design and returned to the four-wire system. If you have the previous design with six holes, below is how you connect the four-wire system.

Each wire is 9 inches (22.86 centimeters) long.

  • One black wire from the switch and one black wire from the power cord makes a double connection.
  • One black wire from the switch and one white wire from the power cord makes the second double connection.
  • One blue wire from the switch and one black wire from the field, and one wire from the power nozzle receptacle, make the first triple connection.
  • One blue wire from the switch and one black wire from the field, and one wire from the power nozzle receptacle, make the second triple connection.

There is no hot and neutral in this application.
