View Full Version : Microswitch installation....

Everybody’s been asking how to install these little 50 gram microswitches so I suppose rather than repetitiously explaining it I would make a tutorial.

First having the correct tools always helps so here are the tools that will come in handy to complete the job.


1) Remove the grips, battery and don’t forget about the nuts under the grips so you don’t lose them.

2) Remove the plug connector from the electronic board. You can just use a small flathead precision screwdriver and put it between the plug connector and board receptacle.


3) Punch the pin that holds the trigger in out from the right side of the trigger frame.

4) Punch the microswitch pins(2) from the trigger frame.


5) Pull the microswitch through the front of the trigger frame along with the wires and connector. Be careful not to damage the connector when pulling it through the trigger frame.


6) Unsolder the old switch from the two wires going to the connector. After removed, heat the wire end and remove as much of the old solder as possible. You can either heat it and tap the wire on a hard surface quickly or heat it and use a piece of cloth to quickly wipe the solder off.


7) Solder the two wires back onto the new switch, black to the bottom and brown to the middle. No wires go to the top post unless there is an r/t mod done to your e-frame. Make sure that the button of the switch is at the bottom end where the black wire is soldered.


8) Touch the battery posts to the battery connector and turn the e-frame switch to the ‘on’ position and depress the microswitch button to be sure everything is working properly before proceeding to the next step

9) Pull the wires and plug connector back through the trigger frame being careful not to damage the connector when doing so.

10) Put the microswitch back in place making sure that the button is towards the bottom. Install the (2) pins through the trigger frame and microswitch holes. Tap them back into the trigger frame with a punch.


11) Install the plug connector back into the board receptacle after being sure that all of the wires are in their proper routing orientation.


12) I have 2 small squares if mylar(thin plastic) that I put between the trigger frame and trigger to reduce any wobble or side to side play.


Put the trigger back in and put the trigger pin back in the e-frame then tap it back in with a punch from the left side. You can choose weather if you do or don't want to put the spring back in.

13) Push the wires of the harnesses back into place then reinstall the battery, nuts and grips back onto the trigger frame making sure none of the wires are between the grips and trigger frame and/or battery.

I tried radio shack... There were some switches with out the levers. They just had a steel plate like a pressure plate or something.
