Siemens 3SB3602-4AD11 Key Selector Switch

Product Description

The SIEMENS 3SB3602-4AD11 is a key-operated selector switch designed for industrial control panel applications. This switch uses a removable key to prevent unauthorized operation, making it suitable for machinery, equipment lockout circuits, and process control panels where operator access must be restricted. Licensed electricians and industrial control panel builders typically specify this type of switch in new panel builds and retrofit projects. The unit measures approximately 4.173 inches in length, 1.811 inches in width, and 1.969 inches in height, and weighs 0.260 pounds.

Key selector switches in this product family are used in a wide range of industrial and commercial control applications, including machine tool panels, conveyor controls, pump stations, and HVAC mechanical room control panels. The key-operated design adds a layer of access control that toggle or maintained push-button switches cannot provide. Installation is typically handled by licensed electricians working to NEC panel wiring standards or by certified industrial control panel assemblers.
