2 9 Honeywell Sensing and Control Forapplicationhelp:call Operating Characteristics ELECTROMECHNICL SWITCHES Definitions below explain the meaning of operating characteristics. Characteristics shown in tables throughout catalog were chosen as most significant. They are taken at normal room temperature and humidity. These may vary as temperature and humidity conditions differ. Sketches show how characteristics are measured for in-line plunger actuation. Linear dimensions for in-line actuation are from top of plunger to a reference line, usually the center of the mounting holes. Differential Travel (D.T.)Plunger or actuator travel from point where contacts snap-over to point where they snapback. IN-LINE PLUNGER CTUTION Free Position (F.P.)Position of switch plunger or actuator when no external force is applied (other than gravity). Full Overtravel ForceForce required to attain full overtravel of actuator. Operating Position (O.P.)Position of switch plunger or actuator at which point contacts snap from normal to operated position. Note that in the case of flexible or adjustable actuators, the operating position is measured from the end of the lever or its maximum length. Location of operating position measurement shown on mounting dimension drawings. Operating Force (O.F.)mount of force applied to switch plunger or actuator to cause contact snap-over. Note in the case of adjustable actuators, the force is measured from the maximum length position of the lever. Overtravel (O.T.)Plunger or actuator travel safely available beyond operating position. Pretravel (P.T.)Distance or angle traveled in moving plunger or actuator from free position to operating position. Release Force (R.F.)mount of force still applied to switch plunger or actuator at moment contacts snap from operated position to unoperated position. Total Travel (T.T.)Distance from actuator free position to overtravel limit position. Courtesy of Steven Engineering, Inc.! 230 Ryan Way, South San Francisco, C ! Main Office: (650) !

TEST CONDITIONS Switch contact life is affected by electrical conditions and other factors, such as: temperature, humidity, airborne contamination, vibration, amount and rate of plunger travel, and cycling rate. Our Evaluation Laboratory tests are conducted using procedures and practices common to UL and Military Specifications. The following conditions generally apply. Temperature: Room mbient (70 F, 2 C). Humidity: Room mbient (50%). C Cycle Rate: 60 operations/minute. DC Cycle Rate: 20 operations/minute. On-off Time: Equal and compatible with above cycling rates. Power Factor (C): pproximately 75%. Inductance (DC): MIL-I-8023 Inductor. Circuit Loading: One throw only on a SPDT switch during any test procedure. Both throws are evaluated separately. Travel Plunger: Full switch travel is used. ctuation: Linear motion. Overtravel Force: to 3 lbs. from spring-loaded actuators. MICRO SWITCH believes that with the following voltage and current values and under the test conditions set forth below switch life of 00,000 closures, 95% survival can be expected. It is a starting point for user evaluation and provides guidelines on the switches identified. Because of the numerous electrical conditions listed, not every current and voltage level has actually been tested on every switch and certain figures have been extrapolated. For specific switch selection, customers should evaluate switches under actual application conditions or by simulating all application conditions and requirements. The information set forth cannot substitute for the customer s own product evaulation. It should never be published by a customer as a rating on their product.

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.39 inch (3,53 mm) diameter. RECOMMENDED TORQUE (max.) Mounting screws...3in./lbs.* Terminal screws...in./lbs. Panel 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 requirements. GENERL SWITCH IDENTIFICTION First letter in catalog listing designates: B = W = single-throw (normally closed) Y = single-throw (normally open) Second letter in catalog listing designates: Z = 5-amp version M = 22-amp version = 20-amp version E = 25-amp version BZ/B Series FETURES Operating force as low as oz. (3 grams) maximum Sensitive differential travel as low as.0002 to.0003 inches (0,005 to 0,008 mm) Power 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.

Fig 5 ORDER GUIDE GENERL INFORMTION SPECIL CIRCUITRY SWITCHES Special sequence switches provide unusual circuit control. 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. nother switch BZ/B Series 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. split contact version allows control of the two isolated circuits. Characteristics: O.F.
