This is a remote start button with cable and JST (1.0 mm) header plug. This cable will plug into the jack on the All-In-One timers or can be soldered direct (after you cut off the JST header) into the two holes in the centre of the board on the tiny band burner timers (for experienced electronics people only - if you do this expect some scorching of the coating that seals the timer board). If you would like for me to add a remote start switch to your existing timer please contact me (hummingbirdmodelproducts@gmail.com) to make arrangements. When you order this product a window will pop-up that requests the cable length you require. Please fill this in and don’t forget to tell me the units you are using (cm or inch).
