6 Pin 16A 250V DPDT Momentary Spring Action Rocker Switch

Rocker Switch Big 6 Pin 16A 250V DPDT Momentary Spring Action is a robust electrical component that facilitates precise control over high-current circuits by utilizing a spring-loaded momentary mechanism, consequently ensuring that the switch returns to its neutral center position immediately after release. Furthermore, the Double Pole Double Throw (DPDT) configuration allows users to control two separate circuits simultaneously or manage the polarity of a single DC motor for directional movement. Its high 16A current rating provides ample overhead for demanding power loads, therefore preventing premature component failure under extreme operational stress. The flame-retardant housing ensures long-term safety in industrial environments, however, technicians should always verify the specific wiring diagram to avoid short circuits.

Key Features:

• High Capacity Rating: Supports heavy electrical loads up to 16A at 250V AC, therefore accommodating powerful industrial motors and heating elements.
• Momentary Spring Return: Features an internal spring mechanism that automatically returns the actuator to the off position upon release.
• DPDT Architecture: Provides six terminals to control two independent poles, consequently enabling complex switching tasks like motor polarity reversal.
• Industrial Durability: Utilizes high-impact, heat-resistant polymers to maintain structural integrity in harsh operating environments.
• Clear Operational Symbols: Features laser-etched arrows for directional control and a center circle to indicate the neutral state.
• Secure Spade Terminals: Includes standard 6.3mm male spade connectors to ensure low-resistance electrical connections and easy maintenance.
