Toggle Switch SPST - (ON)-OFF

The Toggle Switch SPST - (ON)-OFF is a momentary single-pole, single-throw switch designed for applications that require temporary circuit activation. Its (ON)-OFF action makes it well suited for marine horns and windshield wipers.

The switch remains OFF in its normal position and activates the circuit only while the momentary ON position is engaged. When released, it returns to OFF, making it a practical choice for intermittent-control applications.

Maintained vs. Momentary Switches

• Maintained: Stays in the selected "On" or "Off" position until you flip it back.
• Momentary (indicated by parentheses like (On)): Returns to its default position via a spring as soon as you let go; used for temporary actions like horns or starter buttons.

Common Configurations

• SPST (Single Pole, Single Throw): A simple two-terminal switch used to control one circuit.
• SPDT (Single Pole, Double Throw): A three-terminal switch that can alternate power between two different circuits or accessories.
• On/Off/On: A three-position switch commonly used to select between different circuits or operating functions.

Momentary (ON)-OFF Operation

The OFF-(ON) configuration keeps the circuit OFF in its normal position and provides momentary ON operation when activated. Parentheses around a switch position indicate that the position is momentary, meaning the switch returns to its normal state when released. This configuration is commonly used for intermittent horn and windshield wiper control.

Marine Electrical Applications

With a 15A rating at 12V DC and two quick-connect terminals, this SPST switch provides straightforward circuit control for compatible marine electrical applications. The maximum amperage rating depends on using appropriately sized fuses and wire for the specific application.

Specifications

Quick-Connect Terminals

The switch uses two 0.25-inch (6.35 mm) quick-connect tab terminals, providing a straightforward connection for compatible wiring and simplifying installation in applications designed for this terminal style.

Electrical Ratings

The switch is rated for 15A at 12V DC, 15A at 125V AC, and 10A at 250V AC. Always use appropriately sized fuses and wire for the specific electrical load and application.
