Basic Switches Standard BZ/BA Series STANDARD BASIC SWITCH CUT-A-WAY The cut-a-way shown is representative of the standard basic switches described in this catalog. GENERAL INFORMATION 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 holes for Types BZ, BM, BA, BE, DT, MT, and 6AS switches accept pins or screws of .139 inch (3,53 mm) diameter. Characteristics as stated are taken at normal room temperature and humidity. These may vary as temperature and humidity conditions differ. GENERAL SWITCH IDENTIFICATION Standard Basic Switches 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. 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, BA and BE switches greater electrical load handling capacity. Other changes in materials and switch design provide operating characteristics, temperature tolerances, and sealing to cover a wide range of special requirements. FEATURES 1 Operating force as low as 4 oz. (113 grams) maximum 1 Sensitive differential travel as low as .0002 to .0003 inches (0,005 to 0,008 mm) 1 Power load switching capability to 25 amperes 1 Motor handling capacity to 2 horsepower at 250 VAC 1 Long mechanical life 1 High temperature constructions for up to +400°F (204°C) 1 Momentary or maintained contact action 1 Alloy contacts available for special application needs 1 Variety of integral actuators 1 Variety of auxiliary actuators 1 Variety of terminal designs 1 Optional sealed plunger and cover 1 Stainless steel snap spring available 1 Military standard construction available with over 50 listings on the MILS-8805 Qualified products list 1 UL recognized, CSA certified 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 = Standard 15-amp version M = 22-amp version A = Standard 20-amp version E = 25-amp version RECOMMENDED TORQUE (max.)

A make-beforebreak switch provides circuit continuity while switching from N.C. to N.O. In another make-before-make switch, upon actuation, one circuit is made an interval before the second circuit. Another switch provides a single pulse or momentary closure of the contacts with each cycle of operation. Double break versions can interrupt greater inductive loads and feature shorting bar construction. A split contact version allows control of the two isolated circuits.
