Momentary switches cause contact transfer if the cable is manually pulled and held. When the cable is released, switch contacts return to their original state. Momentary switches have either direct-acting contacts or snap-action contacts. Cable length may be up to 200 ft. in a straight line for Single Head switches, and up to 400 ft. (200 ft. in each direction) for Duplex Head switches. FEATURES 1 Offered in Single Head and Duplex Head versions 1 Optional direct acting contacts enhance reliability 1 Duplex Head switches cover up to 400 ft. cable spans (200 ft. in each direction) 1 Single Head switches have one normally open auxiliary contact, while Duplex Head switches have up to three normally open and two normally closed auxiliary contacts 1 Four conduit opening thread size options: 1/2-14 NPT, 20mm, PF1/2 and PG13.5 1 Compact size of Single Head switches fits into tight spaces 1 Sealed to NEMA 1, 3, 4 and 13 1 Smart Distributed System output available on Duplex version for monitoring only 1 UL listed 1 CSA certified 1 CE certified 1 Temperature range: –1° to 70°C (30° to 158°F) 1 Available with indicators 1 Duplex versions available with high visibility pilot light TYPICAL APPLICATIONS TYPICAL DUPLEX HEAD SWITCH INSTALLATION 1 1 1 1 1 Conveyors Packaging machinery Assembly lines Process equipment Transfer lines Honeywell 1 Sensing and Control 1 1-800-537-6945 USA 1 F1-815-235-6847 International 1 1-800-737-3360 Canada A65 Limit/Enclosed MOMENTARY (CONTACT SWITCH) OPERATING HEAD Momentary CLS Series Cable Pull Limit Switches are designed for signaling applications; they are not to be used as emergency stop devices.

There is a choice of four different conduit openings: 1/2-14 NPT, 20mm, PF 1/2, and PG13.5. Duplex switches have 3 standard conduit openings with two conduit plugs provided. All switches come with a 1NO auxiliary contact as standard. NEMA 1, 3, 4 and 13 105 operations maximum –1° to 70°C (30° to 158°F) Numbering to EN50013 Zinc die cast An additional auxiliary switch is also available in the Duplex. This auxiliary switch may be configured as 1NO - 1NC direct acting, 2NO - 2NC snap action (monitoring only) or 1NO - 1NC with Smart Distributed System output (monitoring only). Neon and LED indicators are available. A 6 watt incandescent pilot light is available on the Duplex for high visibility at long distances. SMART DISTRIBUTED SYSTEM OUTPUT VERSION The Smart Distributed System Output Version provides Smart Distributed System compatible switch status messaging. The primary contact block (NC) must be wired to the control current. The auxiliary contact block has been replaced with the Smart Distributed System circuitry. Snap action contact blocks and the Smart Distributed Output Version should be used for monitoring only. These types of switches should not be used in control circuits.
