Omega’s rugged OMPBD7 pilot devices offer maximum flexibility and a wide choice for all applications. This 22 mm line is aesthetically appealing and modularly designed to make assembly and interchangeability easy. The OMPBD7 Push Button operators are available in two different body styles to meet every application need. Both operators exhibit a new lower profile stylish appearance while maintaining the rugged performance necessary for demanding environments.
What is Momentary vs Maintained? When a pushbutton is pressed, it will open or close a circuit. A momentary pushbutton will allow the electrical Contact to return to is original position when the pushbutton is released. A maintained pushbutton will keep the Contacts in the changed position, it requires some additional action to return to is original position.
How does Momentary vs Maintained apply to Selector Switches? 2-Way and 3-Way selector switches come in multiple configurations, fixed positions or spring right return, spring left return or both. When you select a position and the switch remains in that position then the switch is considered maintained in all positions. With a spring right return or spring left return selector switch, the return position would be a maintained condition where the spring position would be a momentary position and the change in the Contacts would only apply while the knob is held in position.
What is a Tool-Less Mounting Latch? Quick, reliable and strong, it’s the best pilot device mounting latch available in the industry. Once the push button operator is installed in the panel, the Tool-Less latch pushes onto the back of the operator with a "click". Now you can snap on up to 6 Contact blocks, with no tools.
