The E-TEN1121 is a heavy-duty, single-pole double-throw (SPDT) toggle switch designed for high-current applications. Unlike the 1122 model, this is a 2-position (ON-ON) switch, meaning there is no central "OFF" position. It is specifically engineered to toggle power continuously between two different outputs or to select between two different operating modes.

Specifications

• Model: E-TEN1121
• Switch Type: Toggle
• Circuit Configuration: SPDT (Single Pole Double Throw)
• Position: 2-Position (ON-ON)
• Rated Voltage/Current:
  • 15A @ 250V AC
  • 20A @ 125V AC
• Contact Resistance: 50 Mohm or less
• Insulation Resistance: 1000 Mohm or more (500V DC)
• Dielectric Strength: 1500V AC (1 minute)
• Mounting Hole Diameter: 12mm

Features

• Continuous Operation: Designed for applications where a device must always be in one of two states (e.g., switching between "Auto" and "Manual" modes) without an intermediate "Off" state.
• Industrial Build Quality: Features a solid metal "bat" handle and a high-impact phenolic resin body to ensure durability under heavy manual use and high electrical loads.
• Heavy-Duty Screw Terminals: Equipped with three large screw terminals to ensure a tight, vibration-resistant connection for high-gauge wiring.
• Simple Integration: Fits into standard 12mm dashboard or panel holes and comes with a full hardware kit, including an "ON-ON" indicator plate.
• Low Contact Resistance: High-quality internal contacts minimize heat build-up, which is critical when switching loads near the 15A limit.

Common Applications

• Mode Selection: Toggling between two different control circuits, such as a thermostat vs. a manual override.
• Signal Switching: Directing an audio or data signal between two different paths.
• Dual-Power Selection: Switching an appliance between two different power sources (e.g., Battery A vs. Battery B) where a power gap is not desired.
• Automotive Lighting: Switching between low-beam and high-beam circuits in custom vehicle builds.
