Options. You can choose silver contacts in SPDT (Form C) orSPDT Double-Break (Form Z) for high current applications, or goldcontacts for low current applications. You can also choose from 12operating styles and a broad selection of levers.

Low Energy Version. Encapsulated, hermetically sealed .5 amp 9007 Type XA reed switches provide reliability in very low energy circuits associated with PLCs.

Direct Opening Contacts. XCM-B has slow-break before make directopening contacts that meet IEC 947-5-1 requirements for positiveopening contacts.

Type XCK-P Compact Switches

Compact Family. These plastic body switches are designed for general and medium-duty applications like packaging, light materialhandling and printing presses. The XCK-P features an integral 1/2"NPT conduit opening.

Enhanced Contact Safety. Direct opening action contacts meet IEC 947-5-1 requirements for positive opening contacts. Positivelever-to-shaft positioning ensures direct opening feature.

Options. A wide selection of contact configurations is available. The Type XCK-T wide-body version has two conduit openings. A maintained version with manual reset is also available for safety-related applications.

Type XCK-L Compact Switches

Compact Size. These heavy zinc die-cast enclosure switches are perfect for applications with limited space such as machine tool and material handling.


Flexible. The entire XCK switch family features a wide selection of contact configurations and a complete selection of operatingheads and lever arms.

o f fe rs the most comprehensive ser-

vice network in the industry. We are

committed to supporting Square D

and Telemecanique products in

162 markets throughout the world.

So, no matter where you or your

c u s t o m e rs need sales and serv i c e,

our people are there. Moreov e r,

because we have both support

p e rsonnel and manufacturing facili-

ties worldwide, our people not only

know p roducts, they also under-

stand the requirements of doing

business in international markets.

In addition, ev e ry Square D and

G roupe Schneider plant has earned

ISO 9000 series certification. This

means we have a common, perma-

nent quality management system in

all locations, one that increases the

quality of the product as well as the

entire process. It also means our

p roducts are recognized around

the world for quality.

9007 Type C Industrial Switches

Versatile. Five bodies, 20 heads, and more than 200 lever stylesa l l ow many configurations.

Rugged and Dependable.Two bearings support a 3/8" shaft, theindustry’s largest. Wrap-around lever arm clamp prevents slippingdue to impact. 90° total travel eliminates shaft breakage due to misaligned cams.

Environmentally Sealed. Complete switches are sealed against oil,water and dust to NEMA 6P as standard. VITON® QUADRING®

shaft seal ensures positive sealing. Shaft is industrial chrome-platedto minimize friction and reduce seal wear.

Simple Installation and Maintenance. Built-in cavity holds excesswire. Extended shaft simplifies cam track adjustment. Mode of operation is easily converted.

Type XCK-J Industrial Switches

Precise. With excellent repeatability of .0004" (0.01mm) and a wide variety of heads and lever styles to choose from, Type XCK-Jswitches offer precision sensing for many industrial applications.

Contact Options. Contact configuration choices include SPDT and 2 SPDT snap action, as well as 2 SPDT slow break before make.Direct opening action contacts meet IEC 947-5-1 requirements forpositive opening contacts.

Two Body Styles. Type XCK-J switches are available in plug-in and non plug-in body styles. They come standard with a 1/2" NPTconduit entry, metric available.

9007 Type T Heavy-Duty Switches

Built for Harsh Environments. 9007 Type T switches have extendedoperating and reset forces and heavy-duty contacts that will break20A @ 120V. They also feature an ambient temperature range of up to 220° F and a die-cast zinc lever arm with hardened oil-impregnated sintered iron rollers.

Versatile. There are 15 different contact operating sequences, mostof which may be field converted to ensure responsive delivery ofrequired sequences.

Foundry Version. Extra long shaft bearing makes these switchesextremely rugged and suitable for foundry applications. They aredesigned to prevent lever arm jamming due to sand build-up andthey’ll withstand falling sand up to 300° F.

Type L Heavy-Duty Switches

Flexible. With an extended range of options, Type L switches fitmost mill and foundry applications. More than 80 contact operatingsequences are available in 2-pole and 3-pole configurations includingspring return, maintained, neutral position and two-step versions.

Connector Options. A choice of connector options is availableincluding straight male 4-pin, 90° male 4-pin, and mini-style malereceptacle. Sealed female plugs and cables are also offered.

Extreme Environments. Options are available for high temperature to 350° F, low temperature to -20° F, and high shock and vibration.

Type XCS Safety Interlock

Rugged. These heavy-duty switches are built for demanding applications. The switch and operating head are designed to be very difficult to defeat.

Advanced Contact Design. Direct opening N.C. contacts meet the IECand EN requirements for positive opening contacts per IEC 947-5-1,EN 60947-5-1; and NEMA ICS-5, part 6 (direct opening action).

Locking Options. Type XCS switches are available with or withoutlocking of the actuating key. Locking may be released with a key or remotely controlled through a low consumption electromagnet.Electromagnetic versions are available to lock with or without voltage applied. An emergency key lock override option is standardfor versions locking without voltage.

Type XCS-P/T Safety Interlock

Compact Size. These miniature, plastic body switches provide interlocking for small doors, guards, screens, etc.


Dependable. The switch and operating head are designed to be verydifficult to defeat. As the actuating key is inserted, a latching mecha-nism is triggered which requires considerable force to overcome.

Wide-Body Version. Type XCS-T versions are available which offer a wide-body design with two conduit entries.

Type XY2-CE Cable Pull Switches

Up To 165 ft Cable Length. Normal or emergency stopping for appli-cations requiring cable lengths up to 165 feet. Wide range of acces-sories and hardware available for adaption to many applications.

Emergency Stop Version. Direct opening N.C. contacts meet the IECand EN requirements for positive opening contacts per IEC 947-5-1,EN 60947-5-1; and NEMA ICS-5, part 6 (direct opening action).

Accurate Tripping. Tripping and traction force are adjusted manually using two built-in scales. Positive latching upon trippingeliminates “teasing.”

Pilot Light. Optional pilot light indicates switch status.

Corrosive Environments. Type XY2-CE switches are available in acorrosion-resistant version.

Type XY2-CH Cable Pull Switches

Up To 50 ft Cable Length. Normal or emergency stopping for applica-tions requiring cable lengths up to 50 feet. Shorter cable requiresreduced operating force for tripping.


Right And Left Hand. Symmetrical design allows use of one device for both right and left hand applications.

Easy Adjustment. Integral ratchet allows easy adjustment of cabletension directly at the device. An external visual tension indicator is standard.


Corrosive Environments. Type XY2-CH switches are available in a corrosion-resistant version.
