Mounting clamp, 4 mounting locations
Mounting clamp with four installation points for contact and LED elements from the M22 RMQ range of products. The normal M22-A adapter has three points only. The fourth adapter is required, for example, for 4-actuator buttons and 4 joysticks, as well as for cases when four contacts need to be connected in series.
