Drill Machine Switch Connection Diagram

I went to ebay and found a model number for a 3 8 vsr and used that at the milwaukee site.

Drill machine switch connection diagram. He has not changed the functionality the tool is active only when the switch is pressed in just like the original. Look closely the original had a lock on button to keep it energized if anything his modification has made it safer since his switch does not do this. I need to find the serial number and look it up. I see 4 wires going to the field stator coil s.

Easy to change drill machine switch change or replace. I m not sure what year this drill is. In case anyone is interested i finally found a wiring diagram but it s not b d. When released it disconnects the power just like the original.

Your drill uses pulse width modulation pwm to control the speed. From an electrical standpoint industrial machine equipment and tools from drill presses to multi motored automatic machines. I was hoping if i put a picture up that maybe someone can roughly identify its age and may possibly know where i can locate a wiring diagram as i am trying to button this machine back up so i can move on to other much needed projects in the shop. I am trying to automate the control of an electric drill motor that im taking from a garden variety variable speed drill from harbor freight it has a universal ac motor which i basically undertand and a dpdt switch to reverse direction and a triac citcuit to vary speed.

Because every type of machine has unique requirements for wiring methods operator safety depends on your understanding the differences between rules in the nec and methods outlined in nfpa 79 every type of machine has unique requirements when it comes to operator safety. I would expect a connection to the battery and terminals with a wire out carrying the pwm drive to the motor. Remove the switch handles made a wiring diagram disconnected the wires from the switches connected the wires and the change over switch to the main switch replaced the switch handles changed out the switch button in the hammer drill selector. The schematic shows an ac source but the connections are the same for a battery drill.

A switch with 5 amp contacts should hold up fine.
