Import 3-Spring Return Push Button With Control Box — Buy in wholesale FOB from Supplier in China

The 3-spring return push button with control box from Zhejiang Ninuo Electric Co., Ltd carries the NIN brand and is manufactured in Yueqing, Zhejiang Province. The control station integrates three spring-return push buttons, each with mechanical return to neutral position, arranged for forward-stop-reverse or up-stop-down motor control sequences. The contact configuration is NO plus NC plus NO, allowing separate control of two motor directions with an interposed stop circuit. The unit is housed in a polycarbonate or ABS control box with arrow-marked legend plates for intuitive operator indication.

Available model variants include XB2-B324, XB2-B334, XB2-B339, XB2-B311H29, XB2-B321H29, and XB2-B341H29, each differing in button arrangement, legend marking, or contact block configuration. The spring-return mechanism ensures the operator must actively hold or press a direction command, enhancing safety in hoist, conveyor, and machine-tool applications where accidental latching could cause injury or equipment damage. The contact blocks are typically rated for 10 A at 660 V AC or similar, though buyers should request the exact electrical rating, mechanical endurance, and IP protection class for the specific variant.

This control station suits industrial machinery, material handling systems, and construction hoists where pendant or wall-mounted operator control is required. The arrow labels (forward, stop, reverse or open, stop, close) reduce operator error in high-noise environments. Buyers should confirm cable entry sizes, mounting hole dimensions, and whether the enclosure meets IEC 60947-5-1 or UL 508 standards. Exact operating temperature, vibration resistance, and terminal capacity should be verified with Zhejiang Ninuo Electric Co., Ltd before specification.

Zhejiang Ninuo Electric Co., Ltd operates from No.1, Pioneer Road, Backstreet Industrial Zone, Liushi Town, Yueqing, 325604, Zhejiang Province, China. Liushi Town is recognised as one of China's largest centres for low-voltage electrical appliance manufacturing, with extensive supplier networks for contacts, enclosures, and terminal materials. The company holds a harbor trust tier, but response rate and average response time are recorded as zero, so buyers should initiate contact to assess communication responsiveness before relying on quoted lead times.

The supplier profile does not disclose factory floor area, employee count, revenue, or specific export markets. No certifications are listed in the source data, so claims regarding CE marking, CCC compliance, or ISO 9001 registration must be requested directly from Zhejiang Ninuo Electric Co., Ltd. The NIN brand appears on the product, but trademark registration territory and enforceability should be confirmed if brand protection matters for your market.
