Contact Block Operation
Contact blocks mount directly to the back of the operator. For
reliable operation, the maximum number of contact blocks that
should be installed behind each operator lever is two (four total).
The figure below identifies the circuits activated by each of the
eight possible lever positions. Contact block plungers 1, 2, 3, 4
are depressed (change state) when handle is in the position
indicated by arrows below.
Circuit Activation
Note: Joystick in its resting state, center position, does not activate
contact block plungers.
Ordering Example:
Suppose you are looking for a four-position momentary joystick
without a latch and the following circuit arrangements.
X = Closed Circuit, O = Open Circuit.
Example Circuit Arrangements
The contact blocks and their mounting locations would be as
follows:
