The 1201M1S3ZQE2 is a miniature DPDT slide switch from the 1000 Series, designed for panel mounting with integrated tabs and featuring silver contact material with matte-tin terminal plating. This switch delivers reliable switching performance with a contact resistance below 10 mO typical at 2–4 V DC with 100 mA, and an insulation resistance of 10? O minimum. The device operates across a temperature range of -30°C to +65°C and supports 40,000 electrical life cycles at full load, with an epoxy terminal seal compatible with bottom-wash cleaning processes. Its compact design and RoHS compliance make it well-suited for test and measurement equipment, telecommunications systems, and computer peripherals where space constraints and reliable switching are essential.
