SPDT stands for Single Pole Double Throw. In SPDT switches, there is a common terminal to which voltage and current are applied to the switch, which can be directed to either a normally open terminal or a normally closed terminal. The direction of current flow is usually determined by a mechanical roller lever that actuates the switch. SPDT switches have three terminals: NO (normally open), NC (normally closed), and C (common). Input current enters the switch through ground, creating a circuit with NO (normally open) or NC (normally closed) contacts.
SPDT Switches are Often called 2 way switch. For example, you can use an SPDT switch to turn on the red lamp in one position and turn on the green lamp in another position. A SPDT toggle switch can be used as a simple on/off switch.
