Trigger Switch Overhang Type 153609-00 SW38D for DW708 Miter Saw Speed Control Trigger Button Switch. Switches are commonly replaced parts in power tools. A switch handles all on/off and variable speed functions. They also play a role in electric braking by momentarily reversing electrical polarity. Since switches use mechanical components, they can degrade and wear out over time, eventually requiring replacement. Common signs of a broken or failing switch include: 1. Tool has completely stopped functioning and will not turn on. 2. Tool operates intermittently, requiring multiple attempts to turn on, until it eventually fails to turn on at all. 3. Variable speed function and electric brake are not working properly. Trigger Switch Part Number: 153609-00 This switch is compatible with the DW708 Cut Miter Saw Types 1, 3 & 4 ONLY.
