APEM is a manufacturer that specialises in the production of high-quality electromechanical switches and switch panels. One of their notable products is the APEM piezo switch.

Piezo switches, also known as piezoelectric switches, are a type of switch that uses the piezoelectric effect to detect mechanical pressure or vibration and convert it into an electrical signal. These switches do not have any moving parts, which makes them highly durable and resistant to wear and tear.

APEM offers a range of piezo switches with various features and configurations to suit different application requirements. These switches are typically designed for harsh environments, such as industrial control panels, medical equipment, and outdoor applications.
