Safety Information
WARNING: Electrical work should only be performed by qualified personnel. Disconnect all power sources before installing or servicing this switch. Failure to do so may result in serious injury or death. Always use appropriate personal protective equipment.
Ensure all wiring complies with local and national electrical codes.
Product Overview

Figure 1: Blue Sea Systems 8207B-BSS SPDT Toggle Switch. This image shows the compact design of the toggle switch, highlighting its robust construction suitable for various applications.
The Blue Sea Systems 8207B-BSS is a Single Pole Double Throw (SPDT) toggle switch designed for ON-OFF-(ON) operation. This means it has a stable ON position, a stable OFF position, and a momentary (ON) position. It is suitable for applications requiring reliable switching in various electrical systems.
Installation
- Mounting: Select a suitable location for mounting the switch. Ensure there is adequate space behind the mounting surface for wiring connections. Drill a mounting hole of the appropriate size (refer to specifications for dimensions). Secure the switch using the provided hardware.
- Wiring: The 8207B-BSS is an SPDT switch. It typically has three terminals:
- Common (C): Connect the power input or load to this terminal.
- Normally Open (NO): This terminal is connected to the Common terminal when the switch is in the ON position.
- Normally Closed (NC): This terminal is connected to the Common terminal when the switch is in the OFF position. (Note: For ON-OFF-(ON), the momentary (ON) might be the third position, so verify the specific terminal functions with a multimeter if unsure).
- Testing: After installation, carefully test the switch's functionality before applying full power to the system.
Operating Instructions
The 8207B-BSS toggle switch features an ON-OFF-(ON) operation mode. This means:
- ON Position: Pushing the toggle lever to one extreme position engages the stable ON state.
- OFF Position: Moving the toggle lever to the center position engages the stable OFF state.
- Momentary (ON) Position: Pushing the toggle lever to the other extreme position engages a momentary ON state. The switch will return to the OFF position when the lever is released.
Ensure the switch is used within its rated voltage and current limits as specified in the "Specifications" section.
Maintenance
The Blue Sea Systems 8207B-BSS toggle switch is designed for durability and requires minimal maintenance.
- Periodic Inspection: Regularly inspect the switch and its wiring for any signs of damage, corrosion, or loose connections.
- Cleaning: If necessary, clean the exterior of the switch with a soft, dry cloth. Avoid using abrasive cleaners or solvents that could damage the switch material.
- Connection Check: Periodically verify that all electrical connections to the switch terminals remain tight and secure.
Troubleshooting
If the switch is not functioning as expected, consider the following common issues:
- No Power to Load:
- Check the power source.
- Verify all wiring connections are secure and correct.
- Inspect for blown fuses or tripped circuit breakers in the circuit.
- Ensure the switch is in the correct ON position.
- Intermittent Operation:
- Check for loose wiring connections at the switch terminals or elsewhere in the circuit.
- Inspect for corrosion on terminals.
- Switch Feels Loose or Damaged:
- If the switch mechanism feels faulty, it may need replacement. Do not attempt to repair internal components.
If troubleshooting steps do not resolve the issue, contact customer support.
