1SFA611285R1001

The ABB 1SFA611285R1001 (Model M3SSK3-101) is a 3-position, key-operated modular selector switch designed for momentary, restricted-access control in heavy-duty industrial environments. It features dual spring-return (momentary) operation. The switch automatically snaps back to the center “B” position as soon as the operator releases the key from either the left “A” or right “C” position. It utilizes a standard Roni's 455 key lock. Due to the spring-return mechanism, the key can only be removed when the switch is resting in the center “B” position.

This is a non-illuminated component. As part of ABB’s modular range, it does not include electrical contacts out of the box; the required Normally Open (NO) or Normally Closed (NC) contact blocks must be snapped onto a back holder separately.
