Impulse switches
Function
Impulse switches are electromechanical or
electronically controlled switches used to control
single or multi-phase medium-power loads while the
control itself can be (very) low power. The device
switches between 2 stable positions, each time a
(brief) impulse energises its control circuit. Typical
applications are given in figure 1 to 4.
Electromechanical impulse
switches
In these devices, the two stable positions are
established by means of a mechanical cam-
mechanism that operates the contacts. The moving
part of the coil pushes the cam-mechanism in to its
next state each time the coil is energised.
Photo 1 shows the front view of the
electromechanical impulse switches.
The main characteristics of the device are printed in
the upper part of the device
1 . These are:
- Switching capacity
- Coil voltage
- Wiring diagram
- 6-digit ordering code
Related to the switching capacity, two families exist:
16A and 25A.
In both families, the following coil voltages are
standard and available of the shelf: 12, 24, 48, 230
and 240V, and 12 and 24VDC.
Manual operation is possible by means of the toggle
2 on the front of the device.
The position of each contact is shown at all time by
means of a mechanical indicator
3 .
The circuit that is operated by this impulse switch
can be indicated behind the circuit indicator
4 i.e.
hall, living, garage, … .
The Pozidriv terminals

are clearly marked and are
all captive.
