Abstract
Relay having contact springs operated by a shifting member, which is mechanically held in one or two end positions. The shifting member is shiftable by one or two magnetic drive systems. It is provided with two over-center springs at one end or at each end. The over-center springs bear at one end on the movable shifting member and on the other end on a fixed point, which is connected to the body of the relay. Monostable relays are provided with a return spring.
Claims16
A relay having contact springs operated by a shifting member which is mechanically held in either one or the other of two end positions, comprising:
- a shifting member;
- a pair of magnetic drive systems each of said magnetic drive systems including an armature for shifting said shifting member from one of said end positions to the other of said end positions;
- a pair of overcenter springs coupled to said shifting member at each end thereof such that said overcenter springs bear at one end on said movable shifting member and at the other end on a fixed surface which is connected to said relay;
- abutment bearing means on said shifting member and on said fixed surface arranged such that one end of said overcenter springs bear on the abutment bearing means on said shifting member and the other end of said overcenter springs bear on the abutment bearing means on said fixed surface, said abutment bearing means further arranged such that the difference between the distance between the abutment bearing on said shifting member and the distance between said fixed abutment bearings is between zero and substantially the length of the shifting movement of said shifting member.
A relay having contact springs operated by a shifting member which is mechanically held in one end position, comprising:
- a shifting member;
- a magnetic drive system including an armature for shifting said shifting member from said one end position;
- a pair of overcenter springs coupled to said shifting member at said one end thereof such that said overcenter springs bear at said one end on said movable shifting member and at the other end on a fixed surface which is connected to said relay and which includes a return spring thereon;
- and
- abutment bearing means on said shifting member for receiving one end of said overcenter springs and further abutment bearing means on said fixed surface for receiving the other end of said overcenter springs and arranged such that the abutment bearings on said shifting member are substantially aligned with said further abutment bearings and said shifting member includes shoulder surfaces which are engaged by contact springs to constrain said shifting member.
