Many of the components used are scavenged (which is why some are overkill) but most items I purchased from Amazon or Jameco. What Amazon & Jameco don’t have I get from Allied or Digikey. I have listed my purchases from Amazon shopping history. For scavenged items like variac I have listed compatible item from Amazon &/or Jameco. Purchasing from affiliate links earns me a small commission and helps support this website. Thanks!

*denotes products I did not get from Amazon (either scavenged, acquired or purchased from Jameco, Digikey or Allied) or a suitable alternative.
**denotes wish list or items I intend to buy.
All other items pulled directly from my Amazon shopping history.

Run/Inspection Circuit Components

Auto/Insp Circuit Schematic
Auto/Insp Circuit shown on Auto

The example farm belt conveyer circuit above consists of a 2 Position DPDT Maintained On-On toggle switch followed by a SPST Momentary Off/(On) Push Button in series with a 3 Position SPDT Momentary (On)-Off-(On) Center return toggle switch.

Although the Up/Dn switch in the schematic is a SPDT (O-F-O) I would use the DPDT listed below which provides an extra set of contacts for flexibility. For example a DPDT switched can be used for a SPDT, SPST or DPST circuit.

Auto/Insp Switch = 2 Position / 6 Terminal DPDT On-On

Enable Button = Momentary Push Button Off/(On) [Normally “OFF”, Push “ON” ]

Up/Down Switch = 3 Position / 6 Terminal DPDT Momentary On-1 / Off / Momentary On-2

Ideal DPDT 774000 Momentary On/Off/Momentary On buy here

Below is an example of a discarded temporary run button rewired using all the available contacts for greater flexibility for a wide variety of uses including barn hoists, winches etc. The run button consist of SPDT Off On Rocker Switch, a SPST Off (On) Rocker Switch & a DPDT 3 position (On) Off (On) Rocker Switch.
