HOMA manufactures DC switches for a variety of DC applications. These can operate under voltages of up to 3.000V DC. The HOMA product range includes switches and switching combinations with positive and negative contacts. HOMA switches are being used for many years in applications that have to operate under high temperatures and continue to conduct and switch high voltages. By using silver contacts and therefore having low ohmic losses, HOMA switches improve the energy balance and reduce energy losses. DC switches can reach switching periods of under 16 milliseconds.
