Relay
By installing an exciter on the outer wall of the relay housing to generate gas impact force, the internal components are driven to switch states, thus solving the problem of arcing under high current and achieving rapid arc extinguishing and miniaturization design.

AI Technical Summary
Technical Problem
Existing relays are prone to arcing under high current conditions, making them difficult to disconnect effectively and affecting the safety protection effect.
Method used
An exciter generates gas impact force to drive the internal components to move, switching the relay from the closed state to the open state. The exciter is installed on the outer wall of the housing and the through hole is sealed to avoid occupying internal space.
Benefits of technology
It achieves rapid arc extinguishing, improves the anti-sticking properties of moving and stationary contacts, and promotes the miniaturization design and ease of assembly of relays.

Abstract
A relay, comprising a housing, an internal component and an actuator. The housing has a through hole, and the through hole passes through the inner wall surface and the outer wall surface of the housing. The internal component is movably arranged in the housing, and is configured to switch the state of the relay from a closed state to an open state and from the open state to the closed state in response to input signals. The actuator is mounted on the outer wall surface of the housing and seals the through hole; the actuator is configured to generate a gas impact force in response to an activation signal, wherein the gas impact force can drive the internal component to move, so that the relay is switched from the closed state to the open state.
