摘要： A sealed receptacle (20) includes a case (21), a cylindrical member (22), and a closure plate (23). The sealed receptacle (20) is configured to house a fixed contact (31), a movable contact (40), and an arc protection member (60). The arc protection member (60) includes a peripheral wall (61), and a bottom (62). The peripheral wall (61) is configured to conceal a junction between the case (21) and the cylindrical member (22) from the fixed contact (31) and the movable contact (40). The bottom (62) is interposed between the movable contact (40) and the closure plate (23). The sealed receptacle (20) houses a contact pressure provision member (51) configured to bias the movable contact (40) to come into contact with the fixed contact (31). The contact pressure provision member (51) is interposed between the movable contact (40) and the bottom (62) so as to come into resilient contact with both the movable contact (40) and the bottom (62) irrespective of a position of the movable contact (40).

摘要： A heavy current reed switch contact structure comprises at least one set of elastic reed electrode (11, 12) or at least one fixed electrode (12) and an elastic reed electrode (11). The reed electrode (11, 12) is made of a conductive material. Contacts (13, 14) are arranged on opposing surfaces of mutually overlapping ends. A side of the end having the contacts is disposed with an arc discharge device (16, 162). The reed switch employs a specially designed contact structure, and the arc discharge structure device is additionally disposed on the basis of a traditional switch contact structure. As a result, the reed switch quickly transfers to the contact arc discharge structure device an instantons arc generated upon switching the switch contact, thereby easing burnout resulting from an arc on the contact surfaces of the contacts, enabling the contacts to be less prone to being adhered together, and considerably increasing a bearing current and a switching capacity of the reed switch. The heavy current reed switch contact structure has a simple structure and provides a heavy bearing current.
