Toggle Switch Configurations and Their Functions

Understanding the pole and throw configurations of toggle switches helps ensure the right fit for your circuit.

Common Switching Configurations:

SPST On-Off: Controls one circuit with a simple on/off function.

SPDT On-On or On-Off-On: Allows switching between two circuits, often with a center OFF position.

DPST On-Off: Controls two separate circuits simultaneously with one switch.

DPDT On-On or On-Off-On: Operates like two SPDT switches, commonly used in motor reversing.

Maintained vs. Momentary Toggle Switches

Maintained toggle switches remain in position until manually changed, like standard light switches. Momentary toggle switches return to their default position after actuation—ideal for horn or start functions.

You can identify the type by labeling:

(ON) = momentary

ON = maintained

Some switches offer three-position momentary center-neutral configurations for specialized controls.

Marine Toggle Switches and Waterproof Options

Need a marine-grade toggle switch or waterproof toggle switch? Look for sealed toggle switches with:

Dust-tight and water-resistant actuator boots

UV-resistant materials

IP-rated enclosures

These are ideal for boats, ATVs, utility trucks, and off-road vehicles exposed to wet or dirty conditions.

Products to Pair with Toggle Switches:

Electrical Solenoids – for high-amperage control

Solid State Relays – for low-energy circuit switching

Wire Connectors & Terminals – for reliable connections
