Abstract
Abstract remotely controllable relay comprises a rocker pivoted at an intermediate point for rocking at one end in normal or reverse direction in response to forward or backward motion of a movable member of an electromagnet means, and a movable contactor linked to the rocker for contacting with or separating from a fixed contactor in response to the rocking of the rocker. A larger momentum at the other end remote from the pivoted point of the rocker achieved with a smaller momentum of the movable member is utilized to sufficiently separate the movable contactor from the fixed contactor upon contact opening, the smaller momentum movable member allowing the electromagnet means to be minimized in size for a miniaturization of the relay and consumed power saving.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
170 words
A remotely controllable relay wherein a movable member is coupled to a movable core of an electromagnet means a current fed to which is reversible for forward and backward motion of said core along the axial direction of a coil of said electromagnet means, and a movable contactor is linked to said movable member for contacting with and separating from a fixed contactor, both of said movable and fixed contactors being electrically connected to a load, said movable member being shifted in one of said axial direction in response to said current fed in one direction to the electromagnet means to thereby turn ON and OFF a power source circuit to said load, characterized in that a rocker is linked to said movable member for rocking in forward or backward direction in response to said shifting direction of the movable member, and said movable contactor is linked to said rocker for said contacting or separating operation with respect to said fixed contactor in response to rocking direction of the rocker.
Claim 2
Dependent Claim
170 words
A remotely controllable relay wherein a movable member is coupled to a movable core of an electromagnet means a current fed to which is reversible for forward and backward motion of said core along the axial direction of a coil of said electromagnet means, and a movable contactor is linked to said movable member for contacting with and separating from a fixed contactor, both of said movable and fixed contactors being electrically connected to a load, said movable member being shifted in one of said axial direction in response to said current fed in one direction to the electromagnet means to thereby turn ON and OFF a power source circuit to said load, characterized in that a rocker is linked to said movable member for rocking in forward or backward direction in response to said shifting direction of the movable member, and said movable contactor is linked to said rocker for said contacting or separating operation with respect to said fixed contactor in response to rocking direction of the rocker.
Claim 3
Dependent Claim
29 words
A relay according to claim 1, which further comprises an auxiliary contact means actuatable with said rocking of said rocker for cutting said current fed to said electromagnet means.
Claim 4
Dependent Claim
78 words
A relay according to claim 1, wherein said movable member is a movable projection integrally provided to said movable core for forward and backward motion therewith on one side of said electromagnet means in said axial direction of said coil, and said rocker which forming part of a switching-contact operating means as well as said movable and fixed contactors which forming part of a main switching contact means are disposed on said one side of the electromagnet means.
Claim 5
Dependent Claim
20 words
A relay according to claim 3, wherein said rocker is pivotably supported to a coil frame of said electromagnet means.
Claim 6
Dependent Claim
40 words
A relay according to claim 3, wherein said rocker is pivotably supported to a coil frame of said electromagnet means and pivot-connected to said movable projection of said movable core at one end portion remote from said pivotably supported position.
Claim 7
Dependent Claim
67 words
A relay according to claim 5, wherein said switching-contact operating means further comprises a small holding chamber provided on one side of said rocker opposite to said coil frame of said electromagnet means, said chamber including an opening for passing therethrough said movable contactor, and a biasing spring disposed in said chamber for providing to said movable contactor a contacting pressure with respect to said fixed contactor.
Claim 8
Dependent Claim
69 words
A relay according to claim 3, which further comprises a casing defining therein a larger compartment for housing said electromagnet means and a smaller compartment housing said switching-contact operating means and main switching contact means, said casing having a projection for supporting said movable contactor operated to separate from said fixed contactor at a position diviated toward the fixed contactor from a completely separated position following said movable projection.
Claim 9
Dependent Claim
38 words
A relay according to claim 7, which further comprises an auxiliary contact means disposed in said larger compartment with said electromagnet means to be operated by said rocker rocked for cutting said current fed to said electromagnet means.
Claim 10
Dependent Claim
45 words
A relay according to claim 1, wherein said fixed contactor is provided to be partly opposed to only a limited part of said movable contactor, and said opposing parts of said fixed and movable contactors are forming respectively a means for electromagnetically attracting each other.
Claim 11
Dependent Claim
49 words
A relay according to claim 3, which further comprises at least an associated relay comprising only components forming said switching-contact operating means and main switching contact means, a rocker in said operating means of said associated relay being interlocked to said rocker of said relay for simultaneous rocking therewith.
Claim 12
Dependent Claim
61 words
A relay according to claim 7, which further comprises a switch provided in said casing on the side opposite to said smaller compartment for detecting operating state of said main switching contact means, said switch being actuatable through a pushing projection integrally provided to said movable core opposite to said movable projection in response to said reciprocating movement of the core.
