T-H Marine KS-1 Saf-T-Stop Ignition Kill Switch for Single Outboard, Black

The T-H Marine KS-1 Saf-T-Stop is an ignition kill switch designed for single outboard installations, giving the operator an emergency engine shutoff within immediate reach of the helm. The switch works with an extra strong, coiled, self-retracting lanyard that the operator clips to a life jacket or wrist; if the operator is thrown from the seat, the lanyard pulls free and cuts ignition power, stopping the engine. This type of emergency stop switch is required by existing boating safety laws, and the KS-1 is built to meet those requirements.

The switch housing is molded from durable plastic in a black matte finish that resists glare and blends into most helm layouts. It mounts into a 1-1/2 inch diameter hole and requires 1-1/2 inches of clearance behind the panel for the switch body, so it is a straightforward panel-mount installation on the dash or console near the helm seat. The overall switch housing measures 2-3/4 inches by 2 inches. Electrically, it is a simple two-position ON-OFF circuit, making wiring and operation easy to understand for any boater replacing a worn or damaged switch.

While rated for all single outboard applications, this style of kill switch is commonly installed across outboard, inboard/outboard, inboard, and multi-engine boats wherever a single emergency stop circuit is needed at that station.
