90 Degree manual turn phase control selector - has phase and neutral connections 180 degrees opposed and on different levels

摘要

The power distribution switch has a manual turn through 90 degrees to connect to the required phase and neutral circuit. The phase and neutral contacts for each phase are 180 degrees opposed. The design reduces construction costs and increases safety aspects. The switch may be used for two phases upwards. Each phase circuit (3,4) is on a different level to the neutrals (5) but the contacts are set in the same insulator body (2). The earth (6) is centrally located. The switch contacts on the central adapter (7) are 180 degrees opposed as well as on different levels and reach into the body of the insulator (2) to make contact with phase (3,8) and neutral (5,10) in the various 90 degree phase and neutral swtch positions. The earth (12) on the adapter and the contact (6) on the switch body (1) make permanent contact in the base vertical position.
