Double Pole Double Throw Switch (DPDT)
Understanding the fundamentals of DPDT switches
What is a DPDT Switch?
A Double Pole Double Throw (DPDT) switch is an electrical switch that has two separate circuits (poles) and can connect each pole to one of two positions (throws). This configuration allows the switch to control two independent circuits simultaneously while providing two switching positions for each circuit.
Key Characteristics:
- • Two independent poles (circuits)
- • Two throw positions per pole
- • Six terminals total
- • Simultaneous switching action
How DPDT Switches Work
Terminal Configuration
Six terminals arranged as two common terminals and four switched terminals, allowing each pole to connect to either of two positions.
Switching Action
When actuated, both poles switch simultaneously from one throw position to the other, maintaining isolation between the two circuits.
Circuit Control
Enables reversing polarity, switching between two sources, or controlling two separate loads with a single switch action.
