1 For application help: call Honeywell SensingandControl 7 STNDRD BSIC SWITCH CUT--WY The cut-a-way shown is representative of the standard basic switches described in this catalog. GENERL INFORMTION MICRO SWITCH standard basic switches are precision snap-action mechanisms enclosed in accurately molded plastic cases. These switches are carefully manufactured and thoroughly inspected. They are industry known for their compactness, light weight, accurate repeatability and long life. MOUNTING DIMENSIONS Mounting dimensions are included at the end of each product section. They are shown in English and metric equivalents. These dimensions are for reference only. For exacting layout work, request an engineering layout work, request an engineering drawing from the 800 number. Mounting holes for Types BZ, BM, B, BE, DT, MT, and 6S switches accept pins or screws of.139 inch (3,53 mm) diameter. RECOMMENDED TORQUE (max.) Mounting screws...3in./lbs.* Terminal screws...in./lbs. anel mount bushing...-6in./lbs. * Note: Tightening mounting screws above 3 in./lbs. changes operating characteristics and increases the possibility of cracking the case. The type BZ switch design meets most applications needs. Modifications of the standard silver contact design and material, spring configuration, and plunger locations give the type BM, B and BE switches greater electrical load capacity. Other changes in materials and switch design provide operating characteristics, temperature tolerances, and sealing to cover a wide range of special. GENERL SWITCH IDENTIFICTION First letter in catalog listing designates: B = Single-pole double-throw W = Single-pole single-throw (normally closed) Y = Single-pole single-throw (normally open) Second letter in catalog listing designates: Z = 15-amp version M = 22-amp version = 20-amp version E = 25-amp version BZ/B Series FETURES Operating force as low as oz. (113 grams) maximum Sensitive differential travel as low as.0002 to.0003 inches (0,005 to 0,008 mm) ower load switching capability to 25 amperes Motor capacity to 2 horsepower at 250 VC Long mechanical life High temperature constructions for up to +00 F (20 C) Momentary or maintained contact action lloy contacts available for special application needs Variety of integral actuators Variety of auxiliary actuators Variety of terminal designs Optional sealed plunger and cover Stainless steel snap spring available Military standard construction available with over 50 listings on the MIL- S-8805 Qualified products list UL recognized, CS certified Characteristics as stated are taken at normal room temperature and humidity. These may vary as temperature and humidity conditions differ. This section covers only over 100 of our most popular BZ/B type Series catalog listings. If you don t find what you re looking for, it s likely one of the approximately 1800 other active listings will meet your needs. Contact the 800 number. UL/CS Our basic switches are Component Recognized by Underwriters Laboratories, Inc. and certified by Canadian s ssociation. The B, BZ, and BM line is covered as Special Use Switches to UL 105; the BE line is covered as an Industrial Motor Controller to UL 508. gency File References are: B UL File E12252, issued BM UL File E12252, issued BZ UL File E12252, issued BE-1,2,5 UL File E22779, Vol., Sec. 1 BE-R UL File E22779, Vol., Sec. 2
