Why Choose the ABB M2SSK3-302 Key Selector Switch?
The ABB M2SSK3-302 is a durable 2-position maintained key-operated selector switch designed for industrial machinery, automation systems and electrical control panels. Part of the ABB modular pilot device range, it combines key-controlled operation with a black actuator and chrome-metal bezel for secure and dependable machine control.
This selector switch uses key code 421 and operates between the B and C positions, with the key removable in position B only. Its maintained switching action keeps the selected state engaged until deliberately changed, making it particularly suitable for authorised operating-mode, enable and maintenance functions.
The M2SSK3-302 is a non-illuminated operator designed for a standard 22 mm panel cut-out. It is supplied without a contact block, allowing suitable ABB modular contact blocks to be selected according to the control-circuit requirements, while its IP66 front protection supports reliable operation in demanding industrial environments.
