Control unit for marine engines employing safety stop switch

Abstract

A safety stop switch for a marine engine includes a control unit housing, and a normally closed, single throw toggle switch mounted on the housing and including a switch arm extending away from the housing to permit operation of the switch between closed and open positions. The switch is electrically connected to the engine to interrupt engine operation when switched to the open position. A hood extends from the periphery of the housing and covers the switch arm when in the closed position, and has a peripheral lip which is spaced from the switch arm a dimension which is less than the thickness of a key which encircles the switch arm. A lanyard is connected to the key and to the boat operator, and upon the exertion of a force on the lanyard, the key pulls the switch arm down into the open position, thereby interrupting operation of the marine engine.
