We decided to size basis looking for ON-OFF switch was not used in the momentary Once you have confirmed at the time of arrival. The item description was not sure of was the only description of the OFF-ON. But the manufacturer catalog as seen after the arrival did not make a mistake if a similar explanation because there was a description of the momentary. Professional only you can thank the description does not mean that to buy.
