How the TM-1901 Rotary Switch Works

The operating principle of this Multi Position Rotary Switch is simple yet highly effective.When the user rotates the shaft,an internal gold-plated movable contact travels across a series of fixed terminals.

Each 40-degree rotation locks securely into one of nine positions.The movable contact then connects the common terminal to the selected output terminal,completing the desired circuit path.This mechanism enables reliable selection of different functions,channels,or operating parameters within electronic systems.
