3-Pin Toggle Switch

Key Features:-

1. Number of Pins: A 3-pin toggle switch has three electrical terminals or pins. These pins are typically labeled as follows:

   • One pin is the "Common" terminal (often labeled as "COM" or "C").
   • The other two pins are the "Normally Open" (NO) and "Normally Closed" (NC) terminals (often labeled as "NO" and "NC," respectively).

2. SPDT Configuration: The 3-pin toggle switch is typically configured as SPDT, which stands for Single Pole, Double Throw. This means it has a single set of contacts (pole) that can be in one of two positions: ON (closed) or OFF (open). The switch can toggle between connecting the common terminal to either the NO or NC terminal.

3. Toggle Lever: The switch is operated by flipping a lever or toggle, which physically changes the position of the contacts, allowing the switch to change the circuit configuration from ON to OFF or vice versa.
