Sealed selector switches simplify assembly

RAFI has expanded its RAMO S selector switch series to include integrated M12 plug and play connectors that simplify assembly. The M12 terminals ensure that the necessary wiring effort is reduced to a minimum and that no extra enclosures with special sealing are required.

Featuring a fully enclosed housing with an IP65 degree of protection, the RAMO S Series does not require an additional housing. Therefore, these switches – like all control and indicator elements in the RAMO 22 and 30 series – are suited for cost-effective construction and retrofitting of decentral applications. Depending on the series, the switches are designed for mounting holes with diameters of 22.3 or 30.3mm.

Alternatively, the RAMO EDGE fixing angle offers the option of placing the switches offset on any surfaces or on 40mm profile rails. The RAMO S series comprises selector switches in different types with rotating angles of 40°, 60° or 90°.

Depending on the model, the levers can be switched to up to three positions and the actuation functions momentary contact, latching or momentary contact and latching. The contact functions available are 1NC+1NO, 1NO and 2NO. The rugged selector switches are also available in illuminated versions with translucent handle marking.

The simple connection with standard M12 plug terminals makes wiring unnecessary, so RAMO switches, key switches and lamps can even be installed by untrained personnel. The components in the RAMO 22 series feature black front rings in synthetic material, while the RAMO 30 versions have flat stainless steel bezels.
