This is a new reproduction Lucas battery cutout switch. It is nicely made and in perfect, new condition. It is similar to the type of switch used on Austin-Healey 100-4, 100-6 and 3000 and some Aston Martins. It would be a great addition for any older car for which you might want antitheft protection or isolation to reduce the likelihood of electrical fires during storage. The big suppliers list this switch for $85.
