Micro switches are widely used in model railway track locators and point motors to detect track positions, switch polarities, and control signals or lights. They act as small, reliable snap-action switches that confirm whether a turnout or track section is aligned correctly. Position Detection: Micro switches confirm the exact position of a turnout or track section.

• Polarity Switching: They can change the electrical polarity of rails when points move, preventing short circuits.

• Signal Control: Often wired to operate panel lights or signals, showing track alignment visually.
