E225SD1V3BE is a sealed snap-acting momentary pushbutton switch from the C&K E020 Series, featuring a single-pole double-throw (SPDT) contact configuration with vertical V-bracket mounting. The switch incorporates an epoxy seal with a disposable splashproof vinyl boot for environmental protection, and is available with gold contact material and gold terminal plating. It delivers reliable performance with contact resistance below 50 mO typical at 2–4 V DC with 100 mA, an electrical life of 60,000 make-and-break cycles at full load, and insulation resistance of 10? O minimum. The switch operates across a temperature range of -30°C to 75°C and provides dielectric strength of 1000 Vrms minimum at sea level. This sealed design makes it ideal for instrumentation, telecommunications, networking equipment, and computer peripherals where moisture protection and long-term reliability are essential.
