The piezo switch is based on the functional principle of the piezoelectric crystal. The action of force
During the voltage drop, the electronic switch contact is closed for the specified pulse duration.
Diagram of an NO switch:
The piezo disk is connected to the terminals 1 and 2. The electric circuit to be switched is
In the neutral position of the piezo switching element, the terminals 3 and 4 are non-conductive,
When actuating the piezo disk, the resistance between terminals 3 and 4 is therefore changed from
This corresponds in principle to the function of a conventional NO pushbutton switch.
on the piezo disk causes a voltage to be induced due to a charge transfer. The voltage generated
is converted by the electronic connection into a polarity-neutral, electronic switch contact.
After this, the electronic switch contact opens again, even if the force is still present. The period
that the electronic switch contact remains closed depends on the actuating speed and force as well
as on the duration of actuation.
connected at the terminals 3 and 4. This can be either direct voltage (DC) or alternating voltage
(AC). If a pulse is applied to the piezo disk, terminal 1 becomes positive in relation to terminal 2 due
to the voltage generated. The integrated switching element controls the electric circuit to be
switched.
and initial contact resistance is greater than 10 MOhm. When the piezo disk is actuated, the initial
contact resistance is reduced to less than 20 Ohm.
