Why Choose the Mersen USMSW2 Auxiliary Microswitch Kit?
The Mersen USMSW2, item number Z227929, is an auxiliary microswitch accessory designed for compatible Mersen UltraSafe™ modular fuse holders. It enables remote electrical indication of fuse-holder operation, helping maintenance teams monitor circuit status from a control panel, PLC, alarm system or building-management platform.
The accessory is particularly suited to Mersen UltraSafe™ fuse-holder installations where remote signalling is required in addition to local mechanical or visual indication. When used with compatible fuse links featuring striker mechanisms, the microswitch arrangement can signal that a fuse has operated, supporting faster fault identification and reducing troubleshooting time.
Supplied as a two-microswitch assembly, the USMSW2 is intended for integration with compatible multi-pole Mersen fuse-holder configurations. Its compact design allows it to be fitted within industrial control panels and switchboards without significantly increasing the overall installation footprint.

Remote Fuse-Status Monitoring for Industrial Systems
Auxiliary microswitches allow the mechanical operation of a compatible fuse link or fuse holder to be converted into an electrical status signal. This signal can be connected to an indicator lamp, audible alarm, PLC input or supervisory control system, allowing faults to be identified without inspecting every fuse holder manually.
The Mersen USMSW2 is particularly useful in installations containing multiple protected circuits, where rapid identification of an operated fuse can reduce machine downtime. The accessory supports more efficient preventative maintenance and fault diagnosis within automated production systems and electrical distribution equipment.
Typical Applications
- Industrial control and automation panels.
- Remote fuse-status monitoring systems.
- PLC input and alarm circuits.
- Motor and transformer protection assemblies.
- Low-voltage switchboards and distribution panels.
- OEM machinery and process-control equipment.
