Part FL15314 is the Fleck Modified Micro Switch, a genuine Pentair electrical component used in the timing circuit of Fleck control valves. The micro switch senses cam position and signals the controller as the valve advances, helping coordinate the precise start and stop of each stage in the regeneration sequence. This position feedback is what lets the controller know exactly where the valve is and when to move it to the next phase.

• Genuine Fleck modified micro switch
• Detects cam position to time valve cycling
• Coordinates regeneration stage transitions
• Available in service kit FL60376-111
• OEM-correct switch for reliable timing
• High-cycle component engineered for repeated actuation

This micro switch has been discontinued as a standalone item but remains available in the FL60376-111 service kit, which bundles it with the related timing and drive parts that are commonly serviced together. Buying the kit ensures the switch arrives matched with its companion components, so the repair addresses the whole timing section rather than a single piece in isolation.

Micro switches are a frequent point of wear in mechanical and electromechanical valve controls because they actuate many thousands of times over a unit's service life. The contacts can erode, the mechanism can lose its crispness, or the switch can fail outright. When that happens, a valve can become stuck mid-cycle, skip regeneration stages, or fail to return to the service position, all of which compromise softening and can allow hard water into the home.

Because the symptoms of a failed micro switch can resemble other control faults, replacing it with the correct genuine part is a reliable way to restore accurate cam sensing and dependable cycle control. As with any electrical service, disconnect power before working inside a control valve, and verify proper operation before returning the system to service so you can confirm the switch is sensing and signaling correctly.

For technicians, sourcing the micro switch through the FL60376-111 kit means the entire timing section can be refreshed in a single, thorough repair rather than chasing intermittent faults one part at a time. Because a worn switch can produce symptoms that mimic other control problems, replacing it with the correct genuine part removes a common variable and restores confidence that the valve will sense its position and cycle reliably for years to come.
