I installed 8 of these Push Buttons in a milking parlor of a dairy farm, They look, feel, and perform excellent. So far I have had to replace one of the buttons because the elastomeric seal where the button is depressed has failed. This could have been an issue with the button being pressed by a hard object like a rake handle or it could have been abused in some other way, I am not really sure what happened. Keep in mind this is one out of eight that needed to be replaced within two years. On year three I think it was the same button had exactly the same issue, now I am thinking that maybe this button just gets used much more than the rest of the buttons. These units have been in a wash down environment with extremely hot water, and soaps and acids and have held up very well so far. The only thing I would change about the button is maybe to decrease the press in distance. I think this might help to prevent pinching of the elastomeric seal.
