ABB M2SSK1-104 is a black non-illuminated 2-position maintained key-operated selector switch with key removal in both positions, random key selection and a black plastic bezel for controlled industrial applications.
£24.60
The ABB M2SSK1-104 is a 2-position maintained key-operated selector switch designed for controlled operator access in industrial machinery, automation systems and electrical control panels. Supplied under ABB order code 1SFA611280R1004, it forms part of ABB’s modular pilot device range and provides secure manual selection between two fixed operating positions.
The M2SSK1-104 features a black key-operated actuator with a black plastic bezel and non-illuminated construction. Both positions are maintained, meaning the selected state remains active until the key is deliberately turned to the alternative position. The key can be removed in both positions, providing flexibility where authorised operating-state selection is required.
This M2SSK1-104 version is supplied as ABB’s random key selection configuration. The order code covers a package of 25 key-operated selector switches with unique key codes, making it particularly useful where individual keyed access is required across multiple machines, panels or operating stations. Contact blocks are selected separately to suit the required electrical switching function.
Key-operated selector switches provide an effective way to restrict changes to machine or process operating states to personnel holding the appropriate key. The ABB M2SSK1-104 combines two maintained positions with key removal in both positions, allowing the selected state to remain active after the operator removes the key.
The random-key configuration is particularly useful where multiple control stations require individual keying rather than a common key. Each package contains 25 selector switches with unique key codes, while ABB’s modular pilot device architecture allows compatible contact blocks and holders to be configured according to the required electrical control function.
