Durability/ Longevity
High, solid-state technology protected thru thin or thick rigid substrates; highly shock/impact resistant
Medium, solid-state design through thin rigid substrates; medium level of shock and impact resistance
Low, highly susceptible to stress or wear in mechanical construction over time
High Low, easily damaged by foreign objects and / or harsh cleaners. Highly subject to wear under heavy use
Low, easily damaged by foreign objects and / or harsh cleaners. Highly subject to wear under heavy use
Surface or Environmental Contaminants
Best units immune to water, moisture and other contaminants or chemical cleaners; wide temperature range
Does not work when wet or moist
Adversely affected by moisture, surface contaminants and changes in temperature
Potential for false actuation or dead zones from surface contaminants
Typical construction easily scratched and degrades with UV exposure; varying performance at different temperatures
