Temco Limit Switches 2018-12-07

Limit Switch Upgrade

  1. CNCMD
    I wanted to have more robust limit switches on my machine. Been through way too many of the micro ones which required tapping the small holes in them that ended up fatiguing the plastic and eventually lead to failure.

    These can be NO or NC.
    Fully adjustable, the "head" rotates, and the arm can be positioned at any angle, etc.
    Full metal construction.
