Moroso 70140 Momentary Contact Spst Switch

Product Description

The MOROSO 70140 is a momentary contact switch wired in a single-pole single-throw (SPST) normally-off configuration. In the normally-off state, the circuit remains open until the operator depresses the switch, completing the circuit only while pressure is applied. This type of switch is commonly used in automotive, racing, and performance electrical applications where a brief, controlled signal is required. Licensed electricians and experienced automotive technicians are the typical installers of this component.

This switch is suited for applications that require a temporary circuit closure rather than a latching on/off function. Common uses include engine start circuits, nitrous activation, horn circuits, and other momentary-trigger functions in performance vehicles and motorsport builds where a normally-off momentary switch is the specified control device.

Key Features

• Momentary contact operation: circuit closes only while switch is depressed
• SPST configuration for simple single-circuit control
• Normally-off default state keeps circuit open at rest
• Designed for automotive and performance electrical systems

Compatibility

Designed as a direct-fit momentary contact SPST switch for automotive, racing, and performance electrical applications requiring a normally-off momentary trigger.

Installation Notes

Installation should be performed by a qualified electrician or experienced automotive technician familiar with low-voltage wiring practices. Disconnect the vehicle battery or isolate the circuit before beginning any wiring work to prevent accidental shorts or component damage. Secure all connections with appropriate terminals and protect wiring runs with loom or conduit as required by the application. Verify switch rating is appropriate for the intended circuit load before finalizing the installation.
