Electromechanical detection
Osiswitch miniature snap switches, featuring electromechanical technology, assure the
following functions:
•
•
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
Osiswitch miniature snap switches incorporate a C/O snap-action, single-break contact. They
are characterized by:
•
•
•
Forces
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).
Minimum release force: value to which the force on the operator must be reduced to allow
the snap action mechanism to return to its rest (unactuated) position.
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
1. Tripping point: position of the operator in relation to the switch mountings (mounting hole
A. Differential travel: distance between the tripping point and the position at which the snap
2. Overtravel limit: position of the operator when an extreme force has moved it to the
B. Overtravel: distance between the tripping point and the overtravel limit.
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 3 mm (0.12 in.) from the end of the plain lever
in the case of a lever operated switch.
Changeover time
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).
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 snap action
mechanisms used, the time is largely independent of the speed of operation. It is normally
less than 20 ms (including bounce times of less than 5 ms).
Operating speed and maximum usable operating rate
Our miniature snap switches are suitable for a wide range of operating speeds: generally,
from 1 mm/mn to 1 m/s (0.04 in/mn to 3.28 ft/s). The maximum usable operating rate on a
light electrical load may be as high as 10 operations/second.
Mounting and operation
To conform to the leakage paths and air gaps in standards EEC 24 - EN/IEC 61058 and
EN/IEC 60947:

Actuation method
Direct operation: 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 45°.
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 that the plunger reaches a point at least 0.5 times
the stated overtravel value of the switch. Also, it should not reach its end of travel nor exceed
the maximum permissible end-of-travel force.

an insulation pad must be inserted between the snap switch and the mounting surface if
the latter is metal,

intermediate actuator made of an insulating material.
The installer must ensure adequate protection against direct contact with the output
terminals.
