Technical Field

The utility model relates to a relay technical field, more specifically say, the utility model relates to a selectable formula electromechanical relay.

Background

Relays are electromechanical switches operated by current in one circuit to control the conduction of current in another circuit. A typical relay basically comprises an electromagnet and a soft iron bar close to the electromagnet, a movable contact connected to the soft iron bar and held in its normal position by a spring. When the electromagnet is energized, it exerts a force on the soft magnetic rod, overcoming the tension of the spring, moving the contacts to close or open the circuit. When the electromagnet is de-energized, the contacts return to the original position. Some relays have multiple contacts, some are hermetically encapsulated, and some have built-in circuitry that delays the contact closing after actuation; some relays are step-by-step and some relays are self-holding.

A machine relay switch is a special type of electromechanical switch in which a Radio Frequency (RF) signal is connected or disconnected between terminals in the switch. In general, the conventional electromechanical relay can only control one channel, and cannot select a corresponding channel to guide the channel according to requirements, so that the performance of the electromechanical relay is not strong enough. And a plurality of channels need a plurality of electromechanical relays to control, thereby increasing the circuit complexity and reducing the safety of the circuit.
