The Maximum Finger Switch DIS-214 is a reinforced version of the Optimum Finger Switch DIS-213. It is of a better quality so it lasts longer over the time. You would opt for this version if you work long shift hours using the finger switch. It has the advantage of a slightly wider inner diameter therefore it will accept easier cartridges that have a label on it and won't tend to split. If your cartridges have a label on it, then it is the perfect choice.
It comes with 2 or 3 pin holes or a jack plug and is compatible with our DIS-115 and DIS-127 dispensers.
