just to help, this is a latch button, NOT momentary. These are excellent switches though. Does DFR plan to offer momentary or can we order momentary switches?

The button SKU:FIT0115-R (Above) works just like the ones you have listed. They are NOT momentary, instead they lock into the ON or OFF position. You press them to turn them on, and then have to press them again to turn them off. ON-OFF or self locking are the same. There are usually versions of the same buttons (I've seen them on other sites too, but I like DFR and would rather buy them from you guys) that are also momentary. You press the button and have to hold it to keep it on. The best example for this use is a servo actuator where I want to press and hold the button to lift something but release the button and have it turn off.
