The E-TEN1122 is a heavy-duty, single-pole double-throw (SPDT) toggle switch designed for industrial, automotive, and high-power DIY applications. Unlike standard ON-OFF switches, this model features a 3-position (ON-OFF-ON) configuration, allowing you to switch between two different circuits or power sources while providing a central "OFF" position for safety and isolation.

Specifications

• Model: E-TEN1122
• Switch Type: Toggle
• Circuit Configuration: SPDT (Single Pole Double Throw)
• Position: 3-Position (ON-OFF-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

• Three-Position Versatility: The ON-OFF-ON functionality is perfect for applications requiring direction control (like Forward/Reverse) or selecting between two different power inputs (like Battery/Mains).
• Heavy-Duty Build: Constructed with a nickel-plated metal lever and a high-temperature phenolic base to handle high-current loads without melting or mechanical failure.
• Screw Terminal Design: Features three robust screw terminals that provide a secure, low-resistance connection, essential for maintaining safety in high-amperage 15A/20A circuits.
• Panel Mounting Ready: Designed for a standard 12mm hole. Each switch includes the necessary mounting hardware: two nuts, a locking washer, and a nameplate.
• Stable Centre Off: The middle position physically disconnects the common pin from both outputs, serving as an integrated safety kill-switch.

Common Applications

• Motor Control: Reversing the polarity of a DC motor (Forward-Stop-Reverse) when used in a bridge configuration.
• Power Selection: Choosing between two independent power sources (e.g., Solar vs. Grid) for a single appliance.
• Automotive/Marine: Controlling dual-speed fans, bilge pumps, or switching between high and low-beam auxiliary lights.
• Industrial Panels: Manual override switches for automated systems where a neutral "OFF" state is required for maintenance.
