It is widely used in truck, trailer, and equipment applications where a brief electrical pulse is needed—for example, to engage a starter solenoid, activate a lift gate, or sound a horn. The switch features silver contacts and screw terminals, making it suitable for high-current DC circuits. You would replace it when the switch becomes intermittent, contacts wear out, or the toggle mechanism fails.
