This device converts the momentary contact action of the ROS-4 4-way switch, or any SPST pushbutton switch, into a DPDT action that is necessary to operate Ray Allen servos. You will need one of these relay decks for each servo in your installation. The REL-2 relay deck replaces the REL-1 relay deck.
The REL-2 functions the same as the REL-1, however the wire exit location is on the top. Measures 1.6" (40 mm) x 1.8” (49 mm) x 1.1” (28 mm).
Small, compact and easy to setup. I have 2 of these relays mounted to a plate with terminal strips and mounted under the pilots seat. Wired 4 buttons of my stick grip into them. They work the flaps and trim perfectly.
