Does any body know where we can find the wiring specs for the limiter microswitches?
What specifically are you asking? The current rating is printed on the side of the switch. Use the DC rating if both AC and DC is listed. If you are using them for sensors, then they can be wired with PWM style wiring or #22 or #24 if they are simply being used with the digital inputs on the DSC as they are not power wiring.
See R40 for all power wiring.
