Know Before You Order

Some orders ship faster than others

We stock tens of thousands of parts in our warehouse, and most in-stock orders ship within 24 business hours. Because we specialize in hard-to-find tool parts, some items are sourced directly from the manufacturer after your order is placed and may require 10–14 business days before shipment. We believe in being transparent about timelines so you know what to expect before ordering. If timing is critical, please contact with your part number for an estimated delivery timeframe.

Why does M&M Tool Parts offer parts other companies don’t?

As a family-owned business, we’ve built long-standing relationships with trusted manufacturers across the industry. These partnerships allow us to source specialty parts that are often unavailable through larger retailers or online marketplaces. In many cases, M&M Tool Parts provides one of the few reliable ways to obtain these components — and we work hard to get them to you as quickly as possible.

What should I expect after placing my order?

Our team begins processing orders immediately. If your item is stocked locally, you’ll typically receive tracking information within 24 business hours. For manufacturer-sourced items, we coordinate directly with vendors to secure and ship your order as efficiently as possible. We understand downtime is frustrating, and we sincerely appreciate your patience while we help source parts that can often be difficult to find elsewhere.

  • Left and right handle halves
  • Carry handle
  • Replacement switch and trigger mechanism
  • Wire terminals

  • Installation instructions

Tool Compatibility

Part Function

The switch assembly controls electrical power to the miter saw motor when the trigger is operated. The complete kit also replaces the associated handle components required to accommodate the updated switch configuration.

When to Replace the Switch Kit

A worn or damaged switch assembly can cause several electrical and operational problems. Common symptoms that may indicate replacement is necessary include:

  • Miter saw does not turn on when the trigger is pressed
  • Intermittent power during operation
  • Trigger or switch feels loose, damaged, or unresponsive
  • Saw unexpectedly shuts off during use
  • Visible heat or electrical damage around the switch assembly

Why This Is a Complete Kit

The original switch configuration used on compatible saws was superseded by an updated design. The 5140112-17 provides the switch along with the necessary handle components, terminals, hardware, and installation instructions required to convert the saw to the replacement configuration.

Replacement Note

A miter saw that will not start or operates intermittently may also have problems with the power cord, brushes, wiring, motor, or other electrical components. Diagnose the saw before replacing the switch kit to confirm that the 5140112-17 is the required repair part. Disconnect the saw from power before performing any inspection or repair.
