Schurter MSM II MO Metal Push Buttons

Posted on the 11 October 2023 by Epreston
New Generation of Mechanical Pushbuttons made of High-Quality Stainless Steel
  • Increased impact resistance IK 08
  • Increased ESD resistance
  • Reduced installation depth
  • Extended standard portfolio

The MSM push-button family has been successfully used on the market for over 30 years. It is known for its durability, precision and particularly high-quality workmanship. These characteristics - combined with additional features - distinguish the new MSM II generation to the same extent.

Expanded Standard Portfolio
A large number of variants have been included in the standard portfolio. For example, the new point illumination. In addition to point illumination, this also applies to the ring and area illumination variants, which are available in a wide variety of lighting colours. Here, the customer is spoilt for choice. There is a choice of different colours as well as RGB versions that allow individual settings and light scenes.

All lighting variants are available for operation on a 5, 12 or 24 VDC supply voltage.

Improved Features:
The MSM II family has not only improved in appearance, but also in technical features. The most important are:

  • Increased ESD resistance (contact: ± 8kV; air: ± 15kV)
  • Increased impact resistance IK 08
  • Even wider temperature range from -30 °C to +85 °C

Subminiature Microswitch
The familiar MSM push-button with microswitch and switching currents from 100 mA to 10 A is now joined by a subminiature microswitch. This has been made considerably smaller again, so that installation is no longer a problem even with minimum installation depths. This additional design is available for switching currents from 100 mA to 3 A for SPDT as well as DPDT circuits.

Unrivalled Haptics
Increasingly high demands are being placed on design. Intuitive operation plays a major role to ensure the safety of the operating process through clear feedback. Thanks to their unrivalled haptic feedback, MSM switches are very popular, especially in combination with optical feedback (ring, point, area
