The Deca A20B-A4E11B maintained push button has a black mushroom head with a 1NO/1NC contact arrangement. Made for 22mm mounting holes. Contacts are silver, with a maximum voltage of 600V and thermal current of 10A.
Not illuminated. A detachable contact block makes installation or removal easier. It has a matte finish to minimize reflections, with a removable push button operator. A maintained push button switch differs from a momentary switch in that it stays in a constant state, whether activated or not, until it is pressed, which changes the state until it is pressed again. Rated IP 65. Complies with EN standard
