Baomain Self-Locking Push Button Switch 3-Phase

The Baomain BMBSP-330/TBSP-330 model is a compact, three-pole solution designed for 3-phase 380V systems. It provides a secure self-locking action, where pressing ON locks the circuit and OFF immediately disengages the connection. Rated for 30A and approximately 3.7KW, it fits neatly into standard control panels with dimensions around 3.5” x 1.8” x 2”. This balance of power handling and footprint makes it suitable for industrial machines, conveyor systems, and automation panels that require robust control interlocks without frequent cycling.
Xiaoyztan TBSP-330 3 Phase Push Button

The Xiaoyztan TBSP-330 focuses on 3-phase ON/OFF control with self-locking mechanics, suitable for mechanical equipment control stations. It uses a slow-moving double-break bridge contact structure with a silver alloy contact for reliable switching. The unit is surface-mounted and designed for single-box integration, with a “Stop” button preceding “Start” for safe motor control in industrial setups. Its simple implementation reduces wiring complexity while delivering consistent 3-phase control performance in factory environments.
mxuteuk 3 Phase Push Button Switch

The mxuteuk AC 220V/380V push button switch offers a 3-phase on/off operation with latching functionality. Rated for 10A, it provides a compact footprint around 100 x 60 x 54 mm, enabling easy panel seating. The product emphasizes reliability through a structured service promise, and its overall dimensions accommodate numerous control panels without crowding. It suits light to moderate industrial loads and is a practical choice for small-to-medium machinery applications where space is at a premium.
ULXIOM Enclosed Motor Disconnect Switch

The ULXIOM enclosed motor disconnect switch offers IP66-rated protection and a 3-phase 35A rating for 440VAC systems. This model emphasizes safety with a sealed enclosure, waterproof design, and straightforward installation. It’s well-suited for outdoor or harsh environments where dust, water, or incidental exposure could compromise equipment. The switch provides immediate circuit shutdown on demand, reducing risk during maintenance and providing clear isolation for personnel working on electrical systems.
Electrical Buddy CBSN-330 3 Phase Pushbutton

The CBSN-330 from Electrical Buddy is a self-locking ON/OFF pushbutton designed for 3-phase systems at 380VAC and 30A. Its compact size supports straightforward panel installation while delivering reliable locking behavior for industrial equipment. The unit is suitable for machinery starters, conveyors, and other heavy-duty control applications where a secure engage/disengage action is necessary for safe operation.
mxuteuk Waterproof Push Button 10A

The mxuteuk waterproof push button is designed for motor on/off control with self-locking action. Rated for 220V/380V and 10A, it’s intended for indoor use where environmental protection is desirable. Its dimensions are optimized for compact control panels, and the design emphasizes reliability with a protective waterproof feature and a straightforward latch mechanism suitable for repeated cycling in variable conditions.
Buying Guide: Key Considerations For 3-Phase Push Button Switches
- Voltage and current rating: Match the switch to your system voltage (220V, 380V, or 440VAC) and load current. Higher-power machines may require 30A or more to handle startup surges.
- Locking mechanism: Decide between self-locking (ON/OFF) versus momentary or non-locking types. For safety interlocks and equipment protection, self-locking designs are typically preferred on control panels.
- Number of poles and phase compatibility: Ensure the switch supports 3-phase wiring and three poles to fully isolate a three-phase circuit when off.
- Enclosure and environmental rating: If the switch will be exposed to dust, moisture, or outdoor conditions, select IP-rated or enclosed models (e.g., IP66) to protect electrical contacts and wiring.
- Mounting and footprint: Check the panel cutout dimensions and overall size to fit the available space in your control cabinet without crowding.
- Electrical isolation and safety: Look for quick-disconnect capabilities and explicit isolation when servicing equipment to minimize risk to operators.
- Durability and maintenance: Consider contact materials (silver alloy contacts are common) and the anticipated duty cycle for high-frequency operation.
- Wiring and terminal compatibility: Verify terminal types and any required adapters for seamless integration with existing control circuits.
- Warranty and vendor support: A clear warranty and reliable after-sales support help address defects or replacements promptly.
When selecting among the options above, consider your primary application—indoor panel control, outdoor equipment, or rugged industrial machinery. Prioritize locking reliability, appropriate current capacity, and environmental protection to ensure long-term performance and operator safety in demanding 3-phase environments.
