Selector Push Buttons

A selector control push button (maintained selector button) is a button whose front element is turned to one of two or three positions and which opens and closes its contacts depending on the position it is in; it is selected by number of positions, maintained or spring-return operation, contact arrangement and, on illuminated models, lamp voltage. It is used to set operating positions such as automatic-manual, on-off or forward-stop-reverse from the panel. The category includes 22 mm mounting diameter models with 0-1 and 1-0-2 positions, maintained and spring-return, non-illuminated or illuminated with 24 V AC/DC and 220 V AC, from the brands Schneider Electric, Isıso, Gwest and Konsan. In the maintained type the selector stays in the position where it is left, while in the spring-return type it returns to the starting position when the hand is removed; the maintained type suits a continuous operating mode and the spring-return type suits a momentary command. Contact arrangements are offered in combinations such as 1NO, 2NO, 1NO + 1NC and 2NC; verify from the product's wiring diagram which contact closes in which position. A selector button is not a substitute for a cam switch that directly switches the load current; its contacts are designed for control circuits.
