{"product_id":"kussmaul-safety-lock-4","title":"Kussmaul Safety Lock 4","description":"\u003cp\u003eThis simple, low cost controller bypasses the ignition switch when activated by the closure of a momentary switch. The operator may then remove the ignition key without shutting the engine down. Movement of the vehicle is prohibited by interlocking the SAFETY LOCK 4 with a switch operated by the foot brake, a neutral safety switch on the gearshift or a parking brake operated switch. Operating any one of these will cause the relays in the SAFETY LOCK 4 to drop out and interrupt the ignition circuit to stop the engine. The authorized operator need only insert the key, and turn on the ignition to operate the vehicle. With the key in the lock and turned on, the ignition circuit is completed as normal and the opening of the SAFETY LOCK 4 relays haS no effect on engine operation. \u003c\/p\u003e\n\u003cp\u003eThe Safety Lock 4 contains 4 relays to permit energizing 3 auxiliary circuits in addition to the ignition switch bypass.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eFour Relay\u003c\/li\u003e\n\u003cli\u003eActivated when ignition key removed\u003c\/li\u003e\n\u003cli\u003eWhen activated, engine remains on and shuts down automatically if controls are manipulated in attempts to move vehicle\u003c\/li\u003e\n\u003cli\u003eSafety Lock override\/re-start when ignition key is inserted\u003c\/li\u003e\n\u003cli\u003e30A relay contacts\u003c\/li\u003e\n\u003cli\u003e3 year warranty\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Kussmaul Electronics","offers":[{"title":"Default Title","offer_id":42691620864061,"sku":"091-160","price":176.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0066\/4289\/2861\/files\/kussmaul-safety-lock-4-safety-lock-kussmaul-electronics-fire-safety-usa-1203127789.jpg?v=1762380873","url":"https:\/\/firesafetyusa.com\/products\/kussmaul-safety-lock-4","provider":"Fire Safety USA","version":"1.0","type":"link"}
