6000 & Reliant'22 Series
Series 6000 and Reliant'22 Contact Selection
1. Determine how many contacts are required for the application, and what contact closure sequence is
needed for each contact.
a. 2-Position Operators: There are only two practical possibilities for contact closure sequence. Using "O" to
indicate an open and "X" to indicate a closed contact, the options are shown in the table to the right. All Reliant
22 and Series 6000 2-position selection selector and keylock operators provide these options.
b. 3-Position Operators: There are six practical possibilities for contact closure sequence. Using "O" to indicate an
open contact, and "X" to indicate a closed contact, the options are shown in the table to the right. Four different
cam types are available to provide various combinations of contact closure sequence. Cam Type 2 (see table
below) provides the most popular closure sequence, and Cam Type 3 provides all six possibilities, depending on
the contact block models chosen. Note that each operator has an upper and lower contact block location, and that
the cam profiles are different for upper and lower locations, except for Cam Type 2.
2. Make a truth table similar to that shown in the example at the bottom of the page, in which each contact required
by the circuit of the application is represented. Up to 12 contacts may be used for each operator, depending on the
sequences required and the types of contact blocks chosen.
3. Refer to the contact sequence table (below). Find the cam type that will provide all of the required contact closure
sequences, and note which contact block model will be needed for each circuit contact.
4. Now refer to the tables on pages I5-I6 for 22mm and pages I12-I13 for 30mm to find the operator model that has
the cam type needed in the application and that provides the desired features with respect to action (maintained or
momentary) type of actuator (lever or key), etc.

SELECTOR & KEYLOCK OPERATORS
ALCOSWITCH selector and keylock operators, in combination with the contact blocks
listed on page I8, are designed to fulfill the circuit requirements of almost any 2- or 3-
position control application. Each operator has two locations (upper and lower) into
which contact blocks may be snap-mounted. Up to four contact blocks may be stacked
in each location, the maximum number depending on the contact block models chosen
and the contact closure sequences required. (Note: only one logic level block may be
used in each location.)

position of 2 position operators providing “Make Before Break” action.
Example: An "Off-On-Reset" circuit control requires a 3-position or 2-position
keylock switch. The key is to be removable in the "OFF" and "ON" position and the
"Reset" position must be momentary (spring return from right to center). All
contacts are open in the "Off" position, and two contacts are closed in the "On"
position. In the "Reset" position a third contact must close and one of the contacts
in the "on" position must open. This contact closure sequence is shown by the
following truth table:

Referring to the Contact Closure Sequence Table, it is seen that cam Type 3
provides these sequences. In addition, the contact block models that should be used
are given; model VA0 (or FA0 for contact No. 1, to be installed in the upper contact
block location; model V40 (or F40) for contact No. 2, to be installed in the lower
contact block location; and model V50 (or F50) for contact No. 3, which may be
used in either the upper or lower contact block location, behind one of the other two
blocks. Reference to the operator model listings shows that model RM272 provides
cam Type 3 and has desired momentary action and key removability.
