Push Buttons

Push buttons are control elements consisting of a front element that the operator presses or turns and a contact block behind it, and they transmit start, stop and position-change commands to the machine. They are fitted into a mounting hole cut in a panel door, control box or machine housing, and switch control circuits such as contactor coils, relays or PLC inputs. Select the push button by mounting hole diameter (16, 22 or 30 mm), spring-return or maintained operating mode, NO and NC contact arrangement, lamp voltage on illuminated models, and the IP rating the environment requires. In the subcategories, spring-return, selector (maintained), emergency stop, mushroom-head and double push buttons are grouped separately; there are series from brands such as Siemens, Schneider Electric, ABB and EMAS with plastic and metal front elements. Since in modular series the head, holder and contact block can be sold under separate stock codes, verify the package contents on the product page if the product name does not give contact information.
