Typical pager designs include battery door locks which are molded from hard thermoplastic materi- als. These designs have several drawbacks, notably: Time consuming to design Require precise dimensional control to be effective Susceptible to failure due to foreign matter build-up on their sliding surfaces Ohen require apertures into the pager into which foreign matter as well as electrostatic discharge can ingress The invention illustrated in Figures 1 thru 4 pro- vides a simple and robust method to automatically lock and manually unlock a sliding battery door. The primary advantage of this method is that the Lock Button is molded from a resilient material and as such can provide an effective seal. Additionally, this design eliminates any sliding motion ofthe lock hence is less susceptible to failure due to foreign matter build-up.
