ETs with two SPDT circuits have a magnetic hold in capability in both directions from center. When the lever is in the center position, the circuitry is as shown in the illustration above. When the lever is moved to one extreme position, switch (A) circuit is transferred and switch (B) circuit is unchanged. In the other extreme position, switch (B) circuit is tranferred while switch (A) circuit is unchanged. 65,000 ft Rating Code Voltage Res. Ind. Motor Res. Ind.

Contact your nearest MICRO SWITCH Sales Office for further information. Screw-Four 48UNF x .188 (ref.) long round head screws with lockwashers. Separated by molded phenolic barriers. Terminals Turret Leadwire TOGGLE TYPES Standard -- Tapered matte finish stainless steel. Pull-to-unlock -- Prevents accidental actuation; must be pulled out to change positions. Push-to-unlock -- Guards against accidental operation. The toggle must be depressed approximately .100 inch before it can be moved to either extreme position. Energizing the coil causes the extreme positions to be electrically maintained until the coil circuit is broken. Tab -- Paddle-shaped clear anodized aluminum tab.
