Movement and Vibration Switches
When correctly positioned the switch contacts will react by giving an intermittent change
of state when subjected to movement or vibration.
DESCRIPTION
The products included in this catalogue are all designed to detect motion or movement. Forms of movement are: Tilt, Rotation, Vibration, Shock or Acceleration.
Many of these can also be supplied for surface mount applications.
Tilt Switches
These operate when tilted from the horizontal position. The switch movement required to cause
contact change is called the differential angle. It is very important when designing a tilt switch
to allow for the differential angle and understand that when in the horizontal position the
switch contact may be open or closed.

Tilt Switch Modules
A Tilt Switch can be located inside a sealed (usually plastic) enclosure. Flying leads are
provided for easy connection.
Tip-Over Switches
These operate when the switch is tilted from the vertical position. The angle through which
the switch has to move before operating is called the operating angle. Many of these
switches are omni-directional. Please state whether you require normally open or closed when
ordering.
Tip-Over Switch Modules
A Tip-Over Switch can be located inside a sealed (usually plastic) enclosure. Flying leads are
provided for easy connection.
Acceleration Sensors
These switches can have a normally open, or normally closed contact which will open
or close when the switch reaches the acceleration activation level.
Movement and Vibration Switch Modules
A Movement or Vibration switch can be located in a sealed (usually plastic) housing.

**Movement / Vibration Modules
Due to the unique features of these modules and the wide range of motion and vibration they may be subjected to, we suggest actual testing of these particular models to
determine the suitability of the module for each application.
MS24A/30
This non-mercury sensor has been designed to detect movement or vibration. The sensor will react
when disturbed by giving an intermittent change of state (ie n/o to n/c or vice versa).
The time taken to settle depends on the amount of energy absorbed by the sensor; the settled
state will normally be closed. The sensors contacts, when undisturbed, are normally closed,
however it is possible to mount the switch with contacts open therefore we recommend that appli-
cations look for change of state not contact open or closed. This product offers additional sensi-
tivity adjustment via an internal potentiometer. The output is referenced to 0V and can drive a
transistor or similar device.
MS24P/10
This non-mercury sensor has been designed to detect movement or vibration. The sensor will
react when disturbed by giving an intermittent change of state (ie n/o to n/c or vice versa).
The time taken to settle depends on the amount of energy absorbed by the sensor; the
settled state will normally be closed. The sensors contacts, when undisturbed, are normally closed,
however it is possible to mount the switch with contacts open therefore we recommend that
applications look for change of state not contact open or closed.
CW60A/30
This sealed tilt sensor has a differential angle of 15° Degrees. The output signals are logic
levels with a degree of de-bouncing applied.
The amount of debounce is adjustable via a potentiometer. The output signal can be used to
drive a transistor if required.
