The HW-DB is a dummy block designed as a replacement part for the IDEC HW series of 22mm control units. This component serves as a mechanical placeholder, occupying an unused position in a contact block mounting adaptor where an electrical contact is not needed. Utilizing the HW-DB ensures proper spacing and mechanical integrity within the switch assembly. It is compatible with a wide range of non-illuminated and illuminated pushbuttons, selector switches, and E-stops within the HW family, allowing for standardized configurations.
