To determine the contact targets of Allen-Bradley 800T and 800H Momentary Push Buttons, 2 and 3 position Push-Pull Push Buttons, and 2 position Twist-release Push Buttons, proceed as follows.
1. Identify the CONTACT BLOCK used by looking at the contact block cover plate and nding a Catalog No. such as 800T-XA.
2. Identify the CIRCUIT for which the contact target is desired by looking again at the contact block cover plate for a wiring symbol such as “A”, “B”, “A1”, etc.
3. Refer to Fig 5 and nd the contact block and wiring symbol.
Read across the top to nd the Lens or Cap position. (IN, CENTER, or OUT)
The contact target is at the intersection of the contact block row and position column.
Dual Input Module Kits: 800T-N290 (120 Vac Full Voltage) Power module and lamp
800T-N291 (24 Vac Full Voltage) Power module and lamp
800T-N296 (120 Vac Transformer Type) Relay module.
Flashing Lamp (6V): 800T-N212 Available for any illuminated device which uses the ANSI No. 755 or No. 1866 lamp.
Lamp Installer: 800T-N82 Useful for installation or replacement of incandescent lamps

(Consult A-B Catalog for ordering information)
The contact blocks listed below may be mounted in various combinations on an operator. See operator instruction sheet for any additional contact block limitations.
Two Tiers High Maximum (for mounting instructions see contact block instruction sheet)
Illuminated Push Button Operators Accept One (1) or Two (2) Contact blocks
Non-Illuminated Push Button Operators Accept One (1) to Four (4) Contact blocks
3 position Push-Pull Only
Using the NCLB Contact function on 2 position Push-Pull and 2 position Twist-Release causes the following:
When the button is pushed from the “OUT” to the“IN” position, the mechanical detent action of the operator occurs before the contacts change state.
When the button is pulled from the “IN” to the “OUT” position, the contacts change state before the mechanical detent action of the operator occurs.
800T-XA2 contact blocks must be used only on the second level if stacked.
Mini-blocks may be used on the second level only.
Sealed Switch blocks are not stackable and may be used one tier high maximum.

WARNING: Only Sealed Switch and Logic Reed Blocks may be used on devices rated for Class I, Division 2 Hazardous Locations.
Substitution of the contact block may impair suitability for Division 2.
Exposure to some chemicals may degrade the sealing properties of materials used in the sealed contact blocks.
Normally Open (NO) contacts, sealed switch contact blocks and logic reed contact blocks can not be used for emergency stop control circuits.
WARNING: 800T-N296 is not rated for Class I Division 2 Hazardous Location.
