The 1201M2S5V4BE2 is a miniature DPDT (double-pole double-throw) slide switch from C&K Components' 1000 Series, designed for low-level dry circuit applications with vertical V-bracket mounting. It features gold contact material with gold-plated terminals, providing a contact rating of 0.4 VA maximum at 20 V AC or DC. The switch offers a contact resistance below 10 mO typical at 2–4 V DC with 100 mA, an insulation resistance of 10? O minimum, and dielectric strength of 1,000 Vrms minimum at sea level. With an electrical life of 100,000 make-and-break cycles at full load, an operating temperature range of -30°C to 65°C, and an epoxy terminal seal compatible with bottom-wash cleaning, this switch is well-suited for test and measurement equipment, telecommunications, and computer peripherals requiring reliable miniature switching in compact form factors.
