ON-OFF-ON Switch Technical Guide
Understanding the functionality and applications of ON-OFF-ON switches
What is an ON-OFF-ON Switch?
An ON-OFF-ON switch is a three-position toggle or rocker switch that provides two separate "ON" positions with a center "OFF" position. This configuration allows users to control two different circuits or functions from a single switch while maintaining a neutral off state.
Position 1 - ON
First active position connects circuit A, enabling the first function or device operation.
Center - OFF
Neutral position where both circuits are disconnected, providing a safe off state.
Position 2 - ON
Second active position connects circuit B, enabling the second function or device operation.
