    Siemens Key Switch, 2 Positions, Latching Type - SIRIUS ACT Series - 3SU1100-4BF11-1BA0


    Lock down high-risk electronic systems with this key switch from Siemens. To complete or break the circuit, you rotate the key 90°, where it latches in position until you turn it back. It's a reliable choice for processes that need a high level of safety or security clearance. The unit only turns on and off with the key, so you can be confident it won't activate accidentally and can't be tampered with. You can use this kind of switch for fire alarms, data cabinets and fuse boxes on processing or assembly lines and large or heavy-duty machinery.

    • IP20-rated housing protects the workings against dust and objects over 12mm, like wires or screws
    • Wide operating temperature range between -25°C and +70 °C to withstand harsh conditions
    • Mechanical switching life of 1,000,000 cycles ensures long-lasting use
    • Screw terminals make it simple to wire and achieve vibration-proof connections

    How do I mount this switch?


    The unit slots neatly into a standard 22mm diameter opening in your panel. The two parts of the switch click together through the hole and you can securely tighten the screw from behind.
