Spring-Return Push Buttons

A spring-return control push button is a momentary-contact button that changes its contact only while held pressed and returns to its initial position by spring force when released. It is used for motor start and stop, reset and step-by-step (jog) commands, and for giving signals to PLC inputs. The category includes models with flush, protruding and marked heads, non-illuminated or illuminated with 24 V AC/DC and 220 V AC, with a 22 mm mounting diameter and plastic and metal housings, from brands such as Schneider Electric, EMAS and Isıso. Select the button by contact arrangement, head shape, color, lamp voltage on illuminated models and housing material; an NO contact for the start command and an NC contact for the stop command are the common choices. Color indicates the meaning of the command; red is commonly used for stop, green for start and blue for reset. A spring-return button should not be confused with a maintained button; since the command is given only while the button is held pressed, continuous operation is provided by contactor sealing or a PLC program.
