4-hole mounting type changeover switch

The 4-Hole Mounting Type key lock changeover switch – A Safe, Reliable Power Control Solution for Industrial and Commercial Applications This industrial-grade 16A Changeover Switch is engineered for precision power management in environments where safety, durability, and operational control are paramount. Designed with a key-operated locking mechanism, it ensures that only authorized personnel can activate or deactivate circuits—ideal for high-risk settings such as manufacturing plants, warehouses, and utility rooms. The integrated key lock system prevents accidental operation when the key is removed, significantly reducing the risk of electrical incidents caused by unauthorized access or human error. Key Features: - Dual-position operation: Handle functions only when the key is inserted; locked when removed—enhancing security and compliance. - Customizable key matching: Standard models come with all-matched keys; non-matching keys available upon request (add "-DAN" to product model), supporting up to 100 unique key combinations per unit. - High-current capacity: Rated at 16A, this switch handles substantial electrical loads efficiently, making it suitable for main power distribution, backup generator activation, and heavy-duty machinery control. - Modular contact design: Supports up to 12 switching positions under normal conditions; reduced to 8 positions when set at a 30° positioning angle—offering flexibility based on application needs. - Secure positioning: The key can be removed from any angular position, allowing for safe storage without compromising the switch’s locked state. Detailed Description: This robust Changeover Switch integrates mechanical reliability with smart access control. Its four-hole mounting configuration ensures stable installation across various panel types, while its internal contacts are built to endure repeated switching cycles without degradation. Unlike standard toggle switches, this model enforces a mandatory key requirement for handle movement—a critical feature in facilities where untrained individuals might inadvertently trigger power changes. The switch’s dual role as both an isolator and a directional selector streamlines complex circuit management, enabling users to safely isolate or redirect power flow with minimal effort. Whether used in emergency power systems, lighting controls, or motor control centers, it provides consistent performance and peace of mind. Ideal Use Cases: - Manufacturing facilities requiring strict access control for power systems - Emergency power transfer applications in hospitals, data centers, or telecom hubs - Industrial equipment with manual override capabilities - Public infrastructure installations where tamper-proof operation is essential - Electrical panels in commercial buildings needing enhanced safety protocols User Feedback: Users consistently praise the switch’s intuitive yet secure operation. One facility manager noted, “It eliminates accidental switching during maintenance shifts—it’s like having a built-in safety protocol.” Another user in the energy sector highlighted its durability: “After two years of continuous use in a dusty warehouse environment, the switch still operates smoothly with no wear on the key mechanism.” Frequently Asked Questions: What makes this switch different from regular changeover switches? Unlike conventional models, this unit requires a physical key to operate—ensuring only trained personnel can make power adjustments, which is vital in regulated industries. Can I have multiple unique keys for one switch? Yes, by adding “-DAN” to the product model number, you can configure a custom key set with up to 100 individual, non-matching keys per switch. How many switching positions does it support? Up to 12 positions under standard settings; if installed at a 30° angle, the maximum drops to 8 positions due to mechanical constraints. Is it suitable for outdoor or harsh environments? While not explicitly rated for IP protection, its sealed internal contacts and sturdy construction make it well-suited for indoor industrial spaces with controlled environmental conditions.
