Pull-to-Cheat
ALTERNATE ACTION
These switches have push-on, push-off
operation. The alternate action is at two
levels, with the maintained On position of
the plunger at a lower level than the nor-
mal Off.
PUSH-PULL
When plunger is depressed, it remains
down and maintains circuit transfer.
Switch contacts return to the previous po-
sition when the plunger is pulled to the ex-
tended position.
PULL-TO-CHEAT
Pull-to-cheat operates normally as a mo-
mentary action switch. However, by pull-
ing the plunger beyond the normal free
position, a maintained On position is
achieved.
POSSIBLE VARIATIONS
In addition to the standard quick-connect
.188 x .020 (4,78 x 0,51 mm) terminals,
angled forms and .250 x .032 (6,35 x 0,81
mm) terminals can be provided. DM plun-
gers and faceplates are available in any
combination of white, black, gray, or red.
