Installation Instructions for the MICRO SWITCH Z Series Basic Switches (ZD, ZM, ZM1, ZW, ZX Series) m WARNING IMPROPER INSTALLATION DO NOT USE these products as safety or emergency stop devices or in any other application where failure of the product could result in personal injury. Failure to comply with these instructions could result in death or serious injury. , CAUTION Wiring must be rated to meet or exceed circuitry requirements. • Connecting circuitry must not exceed switch rating. • Wiring connections must be properly secured. • Do not exceed recommended soldering time or temperature. • Do not contact switch housing with soldering device. • Do not exceed recommended mounting screw tightening torques. • Discontinue use if switch has been damaged or cover removed. • Do not apply side loads to actuator or exceed specified travel limits. • Do not operate or store in areas where corrosive gases such as hydrogen sulfide are present. Failure to comply with these instructions could result in death or serious injury. m DANGER IMPROPER USE DO NOT USE these products in hazardous environments where flammable or explosive gases or liquids such as gasoline or thinners, etc., are present. Failure to comply with these instructions could result in death or serious injury. PK 80173 MOUNTING INFORMATION Switch series Screw size Screw type* Tightening torque max.

Setting the travel position so that less than 70 % of the total travel is used may cause poor contact or welding conditions due to an insufficient contact switching force. • The operating device should never force the actuator/ pushbutton to exceed the total travel position. • For switches with angled terminals, insert an insulator separator between the switch body and the PC board (insulator separator thickness 0,2 mm to 0,4 mm [0.008 in to 0.016 in]. SWITCH DAMAGE • Issue 5 WIRING INFORMATION • • • • Connect wires firmly to terminals. Replace wires that have damaged insulation. Use properly sized spade terminals. Provide strain relief when a potential exists for forces to be transferred from the lead wires to the switch terminals. PIN LOCATION GENERAL INFORMATION MICRO SWITCH Z Series switches are precision snap-action contact mechanisms enclosed in molded plastic cases. Switch actuation triggers the mechanical closure of the switch’s contacts. A small amount of arcing between the contacts during contact closure occurs during normal operation. In order to obtain desired switch performance, the switch must be chosen based on the mechanical, electrical and environmental conditions of the application. Z Series switches are designed for use in a wide range of applications. Typical applications include: • Computer mouse • Tape systems • Printers • Copiers Safety and Productivity Solutions (1) COM (3) NO (2) NC Note: The common pin is identifiable by its position on the end of the switch closest to the actuator/pushbutton. The normally open and normally closed contact positions are relative to the common pin, as shown. SPDT CIRCUITRY COM NC NO MICRO SWITCH Z Series Basic Switches When hand soldering switch terminals, do not exceed five seconds at 350 ºC [662 ºF] (exception for ZD Series switches: Do not exceed five seconds at 300 °C [572 °F] or three seconds at 350 °C [662 °F]). Contacting the switch housing with the soldering device may damage the switch housing. Solder joints must not be moved for at least one minute after soldering. When wave soldering, do not exceed five seconds at 260 ºC [500 ºF] or subject to aqueous wash. Use alcohol and swab to clean terminals. Use of no-clean flux is recommended.
