Description

The 25mm Piezo Switch combines a large metal actuator with sealed solid-state switching. It is designed for applications where reliability, cleanability, and long operating life are more important than mechanical switch feel.

Key Features

25mm bushing size with a broad touch surface
Momentary or latching function options
SPST N.O. or SPST N.C. contact arrangement
More than 50 million operating cycles
IP69K sealing at the front and back
Aluminium 6061 T651 or stainless steel 316L material options
Non-illuminated, dot illuminated, or ring illuminated options

Voltage	1-24V AC/DC
Switching current	0.2A / 1A
Pulse duration	125-300ms
Rated breaking capacity	1W
Actuating force	3-5N
Actuating travel	0.002mm
Connection	Wires
Operating temperature	-40°C to 75°C standard
IP protection	IP69K front and back

How It Works

The piezo element generates an electrical charge when the actuator receives mechanical stress. This creates a reliable switching signal without conventional moving contacts, reducing wear in repetitive-use applications.
