Limits, homes, override switch

[JAZZCNC]

You can always use a 3PDT switch like this one below.[U] BUT you don't need any reset for Homes if you keep them on separate input pins.

No Don't use any relay for Home switches just connect direct to the Input pin or pins. The Relay cause a delay and makes homing unrelaible.

You can share one Input for all Home switches provided you use the correct switch type and connection.

If your wanting to share the Switch for both Home and Limits then you can't using the Relay approach for the above reason.
