As you can see in the schematic the 12V battery (or use other voltages) is connected with the plus at terminal T1 and minus at terminal T2. The contact 1 and 4 are connected together as 2 and 3 are ...

The G13 sealed DPDT 15-kV relay handles in-rush currents between power sources and loads. The 48-mm-high, 55-mm-wide device features 30-cm high-voltage flying leads. Standard coil voltages are 12, ...

Delta has improved its motorised coaxial switch family, introducing the smallest DPDT relay switch of its line, the P/N 1743. This device can manage a power rating up to 150W RMS CW and has four N ...

According to a Tyco Electronics application note, “Silver cadmium oxide contacts have long been used for switching loads that produce a high energy arc. Silver cadmium oxide contacts are less ...

The Relays Group of CUI Devices has introduced a line of signal relays for for low-level current switching in industrial, security, test and measurement applications. The will switch up to 2A or 3A in ...

The addition of a components and an unused NC contact to a dc supply provides a power-reducing feature to a relay driver circuit. Electromagnetic relays need much less power for holding than they do ...
