PRODUCT DESCRIPTION

Functional Description: NO Switch

The piezo switch is based on the functional principle of the piezoelectric crystal. The action of force

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.

During the voltage drop, the electronic switch contact is closed for the specified pulse duration.

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.

Diagram of an NO switch:

The piezo disk is connected to the terminals 1 and 2. The electric circuit to be switched is

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.

In the neutral position of the piezo switching element, the terminals 3 and 4 are non-conductive,

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.

When actuating the piezo disk, the resistance between terminals 3 and 4 is therefore changed from

high resistance



low resistance



high resistance.

This corresponds in principle to the function of a conventional

NO pushbutton switch.

Special feature:

The version high impact stands out by increased protection against vandalism especially the impact

strength.
