Product catalog summary
General Specifications
The Series M Miniature Toggles are designed for specific electrical capacities. For resistive loads, silver contacts are rated at 6A @ 125V AC and 3A @ 250V AC, while gold contacts for logic level are rated at 0.4VA maximum @ 28V AC/DC. Contact resistance is 10 milliohms maximum for silver and 20 milliohms maximum for gold, with an insulation resistance of 1,000 megohms minimum @ 500V DC. Mechanical life is rated at 100,000 operations minimum, with electrical life varying by contact material.
Materials & Finishes
The toggle is made of brass with chrome plating, the frame is stainless steel, the bushing is brass with nickel plating, and the case is made of diallyl phthalate resin, meeting UL94V–0 flammability standards.
Environmental Data
Operating temperature range is –30°C to +85°C. Devices withstand humidity levels of 90-95% for 96 hours at 40°C and are tested for vibration and shock resistance.
Installation & Processing
Mounting torque for large bushings is 3.0Nm, and for other bushings, it is 1.5Nm for double nut and 0.7Nm for single nut. Soldering guidelines are provided for both gold and silver contacts.
Standards & Certifications
The switches meet UL and CSA standards, with specific models recognized at 6A @ 125V AC or 3A @ 250V AC.
Distinctive Characteristics
Features include antirotation and antijamming, high torque bushing construction, and high insulating barriers for increased circuit isolation. Epoxy-sealed terminals prevent contamination.
Ordering Information
Details on ordering include pole configurations, circuit types, bushing sizes, toggle sizes, and contact materials, with options for UL and CSA markings.
Additional Features
Diagrams and schematics for various toggle configurations highlight connections and terminal arrangements for different pole models.
Standard Hardware for B1
Standard hardware components for B1 include a hex face nut (AT503M), a locking ring (AT506M), a lockwasher (AT508), and a hex backup nut (AT527M), used for B1 bushings with keyway and locking ring, and B3 bushings with D flat.
Locking Lever & Bushings
Specifications for locking levers and bushings include dimensions and materials, such as brass with chrome plating for levers and brass with nickel plating for caps. Information on maximum panel thickness and standard hardware for models L1, L4, L3, L8 is provided.
Optional Caps & Cap Colors
Various optional caps are available, made from materials like polyethylene and polyvinyl chloride, in colors such as black, white, red, yellow, green, and blue.
Contact Materials & Ratings
Contact materials and ratings include silver over silver for power levels and gold over brass or copper for logic levels, with dual-rated options for applications using identical switches in both logic and power circuits.
Typical Switch Dimensions
Dimensions for various switch types (single pole, double pole, three pole, four pole) are provided, including keyway and threaded specifications.
Standard Hardware for Small & Large Bushings
Standard hardware components for bushings include hex nuts, locking rings, lockwashers, and o-rings, with details on materials and finishes.
Optional Splashproof Boots
Specifications for optional splashproof boots for toggles include dimensions and materials like silicon rubber.

Distinctive Characteristics Miniature Toggles Antirotation design, standard on noncylindrical levers, mates toggle and bushing; bottom of toggle has two flatted sides which fit into a complementary opening inside bushing. Antijamming design protects contacts from damage due to excessive downward force on actuator. High torque bushing construction prevents rotation or separation from frame during installation. High insulating barriers increase isolation of circuits in multipole devices and provide added protection to contact points. Molded diallyl phthalate case has a UL flammability rating of...
