The TRIGGER Remote Momentary Switch Kit allows you to easily modify your TRIGGER remote to provide true momentary functionality, perfect for applications like train horns or any accessory that requires a press-and-hold activation. Installation is simple: gently pry the existing switch out of the remote, place the included spring over the post of the new momentary switch, and press the replacement switch back into the remote, ensuring proper orientation. Once installed, your remote now features a responsive momentary switch for precise control. Each kit includes one momentary switch and one spring.
