Gardner Bender 42210 Universal Starter Switch 15A 12V

Product Description

The GARDNER BENDER 42210 is a universal starter switch designed for 12-volt electrical systems requiring a momentary-on switching sequence. Rated at 15 amps, it activates only while held or pressed and returns to the off position upon release, making it well suited for starter circuit applications. Connections are made via screw terminals, which accept a range of wire gauges and allow for a secure, reliable termination without specialized crimping tools. Electricians and automotive or marine electrical technicians install this switch as a direct replacement or new-installation component in low-voltage starter circuits.

This switch is applicable in 12-volt DC systems where a momentary-on function is required to engage a starter motor or similar load. Typical installations include small engine starters, utility vehicles, marine engines, and auxiliary equipment requiring a brief, controlled pulse of current to initiate operation. Its universal design accommodates a wide range of starter switch mounting and wiring configurations encountered in the field.

Key Features

• Momentary-on switching sequence — circuit closes only while switch is actuated
• 15-amp rating handles starter circuit current demands
• 12-volt DC rated for standard low-voltage starter applications
• Screw terminal connections for tool-accessible, secure wiring
• Universal fit accommodates varied mounting and wiring configurations

Compatibility

Designed as a universal-fit replacement starter switch for 12-volt DC systems requiring a momentary-on switching function.

Installation Notes

Installation should be performed by a qualified electrician or technician familiar with low-voltage DC wiring practices. Disconnect or isolate the battery or power source before removing the existing switch or making any wiring connections. Screw terminals should be tightened securely to prevent arcing or intermittent contact under load. Verify that the circuit load does not exceed the 15-amp rating of the switch before returning the system to service.
