Many electronics devices, such as pagers, contain one or more single pole switches along exterior edges of the housings. Typical switches require fixturing for loca- tion as well as heat shielding during reflow soldering. The electronics device often contains a separate actuator for operating the switch. Also, with the change from CFC cleaning agents to semi-aqueous solvents in elec- tronic assembly cleaning, the additional need to shield switches from solvent and water intrusion during clean- ing has become an issue. This idea uses an elastomeric actuator combined with edge plating on the main PCB to eliminate the need for a separate switch component and the subsequent fixturing and shielding requirements.
