Auerbach. ZF microswitches, also known as snap-action switches, are electromechanical switches that are activated by a spring-loaded mechanism. They are characterized by their compact design, high switching accuracy, and long service life. These switches are frequently used in various industrial, automotive, and household applications.
A microswitch from ZF is triggered by pressing an actuator. This activates a snap mechanism that performs the switching operation regardless of the speed of the actuation. This technology ensures a consistent switching quality.
Typical characteristics of ZF microswitches:
- Contact configurations: SPDT (Single Pole Double Throw), NO (Normally Open), NC (Normally Closed)
- Compact designs
- Long lifetime
- Various protection classes (IP40, IP65, IP67)
- Various connection options such as solder connections or plug connectors – individually configured cables.
ZF microswitches can be found in numerous areas. The following are some examples of applications from various fields:
- Automotive: Door locks, Seat adjustment
- Household appliances: coffee machines, dishwashers/washing machines – possibly devices from the field of ‘white goods’
- Industry: Controls, Linear Drives
- Medical technology: Actuators for medical beds / chairs
ZF places particular importance on quality, durability, and adaptability to customer-specific requirements. The standard portfolio includes various sizes such as miniature, subminiature, sub-subminiature, and ultraminiature.
As part of the development of switches according to individual application requirements, adjustments to housings, actuators, and electrical specifications are possible. But also switch assemblies including project-specific circuit boards, cables, plastic housings or integrated switch solutions with connector interfaces can be realized.
ZF has expanded its switch portfolio with a battery-free and wireless switch – the energy harvesting generator – based on the inductive principle. This generator produces energy through the mechanical actuation of a switching mechanism. The generated energy is used to send radio commands to a coupled receiver. As a wireless solution, it offers flexibility and the possibility to easily and individually retrofit.
The energy harvesting generator from ZF is available in both a monostable and a bistable version and needs to be supplemented with a circuit board for optimal wireless communication. The ZF generator supports the transmission of various radio standards, such as KNX-RF®, EnOcean®, Bluetooth® Low Energy, Zigbee, and of course also custom protocols.
