Why Choose the ABB M2SSK3-104 Key Selector Switch?
The ABB M2SSK3-104 is a two-position momentary key-operated selector switch designed for industrial machinery, automation systems and electrical control panels where access to a temporary control command needs to be restricted. Part of ABB’s modular plastic pilot-device range, it features a black key-operated actuator with a black plastic bezel.
The M2SSK3-104 provides spring return from position C to position B, with the key removable in position B only. This makes it suitable for authorised momentary machine commands where the selector should automatically return to its normal position after operation.
ABB order code 1SFA611282R1004 identifies this exact M2SSK3-104 key selector switch. This random-key variant is supplied in an order quantity of 25 switches, with each selector using a unique randomly selected key code; standard key codes 455, 421 and 3433-E are excluded from the random selection.
Key Advantages
- Two-position momentary key selector for controlled industrial commands.
- Spring return from C to B automatically restores the selector after operation.
- Key removable in position B only provides a defined key-release position.
- Random unique key coding supports applications requiring individually keyed operators.
- IP66 front protection supports demanding industrial environments.
- Mechanical durability of approximately 500,000 operations.

Controlled Momentary Key Operation for Industrial Machinery
Momentary key selector switches provide a practical way to restrict temporary machine commands to authorised personnel. The ABB M2SSK3-104 springs automatically from position C back to position B and permits key removal in position B only, providing a clearly defined normal and key-release state.
The random-key configuration is particularly useful where individually keyed selectors are required. ABB supplies this order code as 25 key-operated selector switches, each with a unique random key code, while the modular construction allows suitable contact blocks to be selected separately for the required electrical control function.
Typical Applications
- Industrial machine control panels.
- Authorised momentary machine commands.
- Factory automation equipment.
- Key-controlled enable and operating functions.
- Applications requiring individually keyed selectors.
- Production and process machinery.
- Conveyors and material handling systems.
- OEM machinery and electrical control systems.
