The new MSM II MO metal push buttons

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.

The elegant design and the enormously wide selection of high-quality push-buttons and switches of all kinds form the foundation for the success of the MSM family for decades. The stainless-steel enclosure is now available with subminiature microswitches, which allow installation in units with a small mounting depth.

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 to +85°C

Subminiature microswitch

The familiar MSM push-button with microswitch and switching currents from 100mA to 10A 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 100mA to 3A 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 lighting).
