Pushbuttons: Quality and reliability from OTTO Controls and NKK Switches

Electromechanical components such as pushbuttons are used wherever every small detail matters. For safety reasons, we rely exclusively on well-known premium manufacturers such as OTTO Controls and NKK Switches, whose highest priority is quality. Pushbuttons are used in electrical circuits that need to be manually closed or interrupted. In order to meet both current and future requirements, many pushbuttons are waterproof or feature other practical characteristics. In addition, we offer pushbuttons with two-step switching (“Two Step”). At ALDERS, you benefit from exceptionally high-quality components and our competitive prices.

For example, we offer pushbuttons with the following features:

  • waterproof pushbuttons
  • pushbuttons with illumination
  • different housing shapes
  • buttons with OLED or LCD display
  • various thread sizes

If you have any questions about pushbuttons and our other products, such as customized pushbutton caps, we will be happy to advise you. Call us or send us an email with your inquiry.


The portfolio of ALDERS electronic GmbH includes technologically leading solutions from the premium manufacturers OTTO Controls and NKK Switches. These components are specifically designed for applications where operational reliability is the top priority – from industrial production systems to highly sensitive applications in the aerospace industry.

Technical Features and Performance Profile

  • Extreme durability: Many models are rated to protection classes IP64 to IP68S. This makes these pushbuttons completely dust-tight and waterproof, making them ideal for use in the harshest environmental conditions.
  • Superior service life: The heavy-duty solutions from OTTO Controls guarantee mechanical durability of several million switching cycles, significantly reducing maintenance costs over the entire machine lifecycle (TCO).
  • Innovative feedback options: In addition to classic LED illumination, ALDERS offers state-of-the-art SmartSwitch solutions from NKK Switches. These integrate OLED or LCD displays directly into the switch to visualize dynamic labeling and complex status messages.
  • Functional versatility: Availability of two-step switching (“Two Step”) for differentiated control commands, as well as various housing shapes and thread sizes for seamless mechanical integration.
  • Standards compliance: For aerospace and defense applications, we offer pushbuttons that comply with strict military specifications (MIL-PRF).
