Abstract

A battery powered condition detecting unit includes first and second battery retaining prongs which in the absence of a battery come in contact with a blocking flange on a cover thereby making it impossible to latch the cover to the unit. In the presence of a battery, the free ends of the battery retaining prongs are spread apart so that the blocking flange drops therebetween allowing the cover to be latched to the unit.
