In industrial control panels, push buttons are the direct link between operator and machine. NOARK push buttons are built to withstand frequent actuations, harsh environments and demanding specifications. Models range from 22 mm cut-outs to DIN-rail mount modules, rated for millions of cycles and IP65+ protection when mounted on machine doors. For procurement, the key checks are voltage rating, contact arrangement (1 NO, 1 NC, etc.), illumination status and whether the actuator head is screw-in or snap-in.
Selector switches control machine states—manual, automatic, service mode. The NOARK selector switches provide clearly differentiated positions, key-lock options and optional illumination for quicker fault diagnosis. Many use the same base as emergency stop modules, which simplifies spare-parts selection. From a design standpoint: check detent positions, smooth operation under load, mechanical life rating, and compatibility with rotation-interlock setups.
Absent a functioning emergency stop, the entire safety chain is at risk. NOARK emergency stop buttons adhere to EN ISO 13850 and IEC 60204 requirements: large red mushroom heads, yellow backgrounds, latching mechanisms and quick-release reset. Look for certifications (CE, UL), ambient rating (-25 °C to +70 °C) and whether the head is illuminated or non-illuminated. Correct specification and standardised replacement parts make maintenance predictable and documentation consistent.
Often, control panels integrate multiple actuators—buttons, selectors, emergency stops—into a single operable unit. The NOARK panel button units deliver this: modular blocks that combine different actuators, share wiring, and snap into panel positions. These units reduce drilling, wiring time and complexity in assembly. When specifying: match panel thickness, mounting cut-outs, actuator spacing, and ensure replacement modules remain within the same series family.
Before placing your order, make sure you review:
Panel-builders and machine manufacturers who standardise on NOARK across their control-interface layer report lower part-number variation, fewer operator errors and simpler spare-kit logistics. When technicians encounter the same buttons and selectors on every machine, training is faster and service documents become predictable—not a mix of brands and styles.
