Overview
How to wire a mechanical switch to replace an optical endstop.
Good reasons
- The flags wont bend.
- Cheaper.
- No need for opto pcb.
- Simple switches can be used on x and y axis.
- You could even make your own contact switch from a few pieces of metal.
- You get to solder stuff.
Bad reasons
- Switches have a limited amount of on/off cycles. (Especially cheap ones).
- Needs new way to mount switch, which will depend on the switch type.
- The resolution and repeated function of the triggered distance is very critical on the z axis.
- You have to solder stuff.
Opto Endstop v1.0, v2.1 and Tech Zone Remix
How to replace Opto Endstop v1.0, Opto Endstop v2.1 and Tech Zone Remix Endstop which share the same basic design.
Interface
Copied from DarwinOptoEndstop#Interface
| Pin | Function |
| +5 | This is the pin to supply +5 volts on. |
| S | This is the signal pin. It will output high (+5) if it is triggered, or low (0v) if it is clear |
| G | This is the ground pin. |
Switch requirements
High resolution aka short trigger distance with high repeatability for the z axis.

Optional LED
If you want an indicator, you can hook up a LED (and a matching resistor).
