Schneider Electric Harmony push-button range

Schneider Electric has announced updated Harmony push-buttons. The updates come after recent changes to the governing industry standards - a trigger-action mechanism head is now prescribed for both Emergency Stop and Emergency Switch-off functions.

The use of standards-compliant emergency push-buttons is a mandatory requirement for all machine installations to protect persons and equipment from mechanical and electrical hazards in accordance with industry standards AS/NZS 3947/IEC 60947 (Low voltage switchgear & control gear), AS/NZS/IEC 60204 (Safety of machinery) and ISO 13850 (Emergency Stop - principles of design).

The new range of Harmony push-buttons has been designed for numerous applications across the industrial, building and infrastructure sectors. They allow for wireless operation of a relay (receiver) through a push-button transmitter enabling the control of machines for distances of up to 25 m. Equipment operators have the added option to send a one-time radio message to one or multiple receivers, or synchronise up to 32 push-buttons with just one receiver, and can provide a significant 20% saving in installation time and cost.

Other features of the Harmony push-buttons include a choice of metal or plastic bezel; push/pull, turn-to-release or key release; 30, 40 and 60 mm sizes; and a range of enclosures, legend plates and accessories.
