GP12MCBE is a sealed ultraminiature SPDT (single-pole double-throw) momentary pushbutton switch designed for compact applications requiring reliable switching performance. The switch features a contact rating of 0.4 VA maximum at 20 V AC or DC, with contact resistance below 50 mO typical at 2–4 V DC and 100 mA. It offers an IP57 degree of protection against harmful dust deposits and temporary immersion, with sealed construction incorporating an internal o-ring and epoxy base for durability. The switch is rated for 40,000 make-and-break cycles at full load and operates reliably across a temperature range of -40°C to 85°C. Its ultraminature design, combined with RoHS compliance and process compatibility with standard soldering and washing techniques, makes it ideal for telecommunications, network equipment, computers, instrumentation, and medical applications where space constraints and environmental sealing are critical requirements.
