Why Choose the ABB M33SK2-101 Key Selector Switch?
The ABB M33SK2-101 is a reliable three-position key-operated selector switch designed for industrial control, machinery and automation applications where restricted or authorised operation is required. Supplied under ABB order code 1SFA611284R1001, it forms part of ABB's modular pilot device range and provides secure manual control from a control panel or operator station.
The M33SK2-101 uses a maintained three-position operating mechanism, allowing the selected position to remain engaged without the operator holding the key. The key can be removed in the centre position B only, helping provide controlled access to machine or process functions while preventing unauthorised changes when the key has been removed.
Featuring key release code 71 / Ronis 455 and a black plastic bezel, the M33SK2-101 is designed for integration with ABB modular pilot device holders and contact blocks. Its modular construction allows the required contact arrangement to be configured for the control function, making it suitable for control panels, machinery, production equipment and industrial automation systems.

Secure Control for Industrial Machinery
Key-operated selector switches provide a simple way to restrict particular machine or process functions to authorised personnel. Unlike a conventional selector switch, operation requires the corresponding key, helping prevent unintended changes to operating modes, machine states or controlled functions.
The ABB M33SK2-101 combines a three-position maintained mechanism with modular ABB pilot device construction. Compatible holders and contact blocks can be selected to create the required electrical switching arrangement, allowing the operator to be incorporated into a wide range of industrial control and automation designs.
