MIL-DTL-2212 Contactors And Controllers, Electric Motor Ac Or Dc, And Associated Switching DevicesThis specification covers alternating current \(AC\) and direct current \(DC\) motor controllers, contactors \(see 6.8.6\), and associated switching devices \(see 6.8.3\). Included are magnetic controllers, controller parts \(see 6.8.52\), limit switches \(see 6.8.90\), pressure switches \(see 6.8.92\), temperature switches \(see 6.8.95\), selector switches \(see 6.8.94\), push-buttons \(see 6.8.57\), and similar devices used for control of electric motors \(see 6.8.19\). Semiconductor \(solid-state\) devices used as parts for magnetic controllers are included.
