Domed heads for release pushbuttons, ZB4-B
The Harmony XB4 metal range of modular control and signalling units combines simplicity of installation, flexibility, and robustness. This range meets the requirements of the majority of industrial applications.
These units are either complete products or separate components for customer assembly.
This range of XB4 includes:
•Pushbuttons, selectors/key switches, emergency stop functions or multiple-headed pushbuttons designed for parameter settings, adjustments, and start/stop control of machines and installations
•Pilot lights, illuminated pushbuttons, illuminated selector switches, and
•illuminated Emergency stop functions designed for visual signalling
The installation process is both simple and quick:
•Mounting by single installer (self-maintaining of the head in its cut-out)
•Clip-together component system (head, body, contact blocks, and LED)
•Attached using a single locking screw
•Anti-loosening system for screw clamp terminals on contact blocks

Environment
The performance of the Harmony XB4 range meets the most demanding international standards and approval, such as:
•EN/IEC, CE marking, UL, CSA, CCC, EAC, JIS, NEMA, and marine approvals
•Protection against ingress of solid objects, dust, and water: IP 66, 67, 69,69K and type 4X
•Shock protection level up to IK06
•High vibration resistance with shake proof connection screws (periodic retightening unnecessary)
For outdoor applications the operating temperature oscillate from -40 °C to +70 °C/-40 °F to +158 °F.

Frequently asked questions & answers
What is the different between a push button switch for an emergency stop and a general-purpose push button switch?
A general-purpose push button switch is used for controls, e.g. to start machine operation or simply to switch modes. An emergency stop push button switch however, is mainly used as a safety measure to stop hazardous events.
What is the electrical shook protection class for this item?
This is a Class 1 conforming to IEC 61140
