Small, Light, and Powerful
Ray Allen Company trim components have been used in RVs for many years. Electric trim requires the use of a small motor, a switch, interconnect wire and in some cases a special purpose relay and a speed controller to slow the response if desired. The servo motor is supplied with a switch which can be mounted on the panel, pushrod/clevis hardware, and an LED position indicator.
