Presentation, terminology, characteristics, mounting Miniature snap switches Osiswitch Miniature design General Presentation XEP XC0 Terminology XEP EWp XEP EFDp XEP Electromechanical detection b Osiswitch miniature snap switches, featuring electromechanical technology, assure the following functions: v detection of presence or absence, v detection of position. Actuation of the operator (plunger or lever) on the miniature snap switch causes the electrical contact to change state. This information can then be processed by a PLC controlling the installation. Osiswitch miniature snap switches can be used both for industrial applications and the building sector. Features b Osiswitch miniature snap switches incorporate a C/O, single break, contact. They are characterised by: v high electrical ratings for their very small size, v short tripping travel, v low tripping force, v high repeat accuracy on the tripping points, v long service life. Forces b Maximum tripping force: maximum force which must be applied to the operator to move it from the rest (unactuated) position to the trip position (tripping point). b Minimum release force: value to which the force on the operator must be reduced to allow the mechanism to return to its rest (unactuated) position. b Maximum permissible end of travel force: maximum force that can be applied to the operator at the end of its travel without damaging the switch. Position / Travel Tripping point: position of the operator in relation to the switch fixings (fixing hole centre line) at the instant the switch contact changes state. A Differential travel: distance between the tripping point and the position at which the snap action mechanism returns to its initial state on release of the operator. Overtravel limit: position of the operator when an extreme force has moved it to the effective end of its available travel. B Overtravel: distance between the tripping point and the overtravel limit. Mechanical characteristics NC NO T T The reference point for the figures given for forces and travel is a point F, which is situated on the plunger in the case of a basic switch or at from the end of the plain lever in the case of a lever operated switch. Changeover time b This is the time taken by the moving contact when moving from one fixed contact to another until it becomes fully stable (contact bounce included). b This time is related to the inter-contact distance, the mechanical characteristics of the snap action mechanism and the mass of the moving element. However, due to the mechanisms used, the time is largely independent to the speed of operation. It is normally less than 0 milliseconds (including bounce times of less than ms). T: bounce time Operating speed and maximum usable operating rate T: changeover time b Our miniature snap switches are suitable for a wide range of operating speeds: generally, from /mn to m/s. b The maximum usable operating rate on a light electrical load may be as high as 0 operations/second. A B C 0 Mounting A B C Mounting and operation b v v b To conform to the leakage paths and air gaps in standards EEC - EN/IEC 0 and EN/IEC 0: an insulation pad must be inserted between the snap switch and the fixing surface if the latter is metal, manual operation of a metal actuator must only be carried out with the aid of an intermediate actuator made of an insulating material. The installer must ensure adequate protection against direct contact with the output terminals. Actuation method b Direct operation: v the plunger should preferably be actuated along its axis. However, the majority of our miniature snap switches will accept skewed operation provided the angle of actuation is not more than. The travel of the actuator must not be limited to only reaching the tripping point. The actuator must always be operated in such a manner so that the plunger reaches a point at least 0. times the stated overtravel value of the switch. Steps must also be taken to ensure that it does not reach its end of travel nor exceed the maximum permissible end of travel force. /
Mounting, characteristics (continued) Miniature snap switches Osiswitch Miniature design General Mounting (continued) Actuation method (continued) b Lever operators: v when actuation is by a roller lever, force should preferably be applied in the direction shown in the diagrams opposite, v where the movements involved are fast, the ramp should be so designed as to ensure that the operator is not subjected to any violent impact or abrupt release. 0 0 A B C A B C Fixing - Tightening torque b The tightening torque of the fixing screws must conform to the following values: Ø of fixing screw.. Tightening torque (cm.n) Maximum 0 00 0 Minimum 0 0 00 Resistance to mechanical shock and vibration b Resistance to shock and vibration depends on the mass of the moving parts and on the forces holding the contacts together. b In general, for a miniature snap switch without accessory: v vibration > 0 gn, 0 to 00 Hz, v shock > 0 gn ms / sine wave. Electrical characteristics Number of cycles 0 0 0 0 0, 0, 0, 0 A Current Resistive circuit Inductive circuit Cos ϕ 0. Operating curves b These indicate the electrical life of the miniature snap switches under standard conditions (0 C, cycle/ seconds), by showing the number of switching operations which can be performed with given types of load. For sealed snap switches, the operating rate is cycle/ s. Insulation resistance b The insulation resistance of the miniature snap switches is generally greater than 0,000 MΩ, measured at 00 V d.c. 00 V Dielectric strength b The dielectric strength of our miniature snap switches is generally superior to: v 00 Volts between live parts and earth, v 000 Volts between contacts, v 00 Volts between contacts for switches with an inter-contact distance less than 0.. 000 V 0 /
