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.
