ABSTRACT:
A novel battery powered lamp is disclosed which includes a hollow housing, a light bulb disposed in the housing for external illumination, a battery in the housing and switch means. In one embodiment, the switch means is a rotary switch having a manually rotatable arm extending through the housing, preferably at the rear end, for movement into and out of contact with a contact plate. In another embodiment, a flexible resilient electrically insulative biasing block is interposed between the bulb and battery and bears contacts. The block preferably supports the bulb while biasing the contacts in place against the bulb and battery. In a third embodiment, the bulb is socketless and has its base embedded in the block so that it is suspended in a transparent portion of the housing. Each embodiment is simple to assemble and use, inexpensive to make and maintain, efficient and durable. All are utilizable as portable flashlights and the like, and are capable of being made weatherproof.
