Abstract
In an electromagnetic relay, a first stationary contact member (25) has a first, elongated portion (25a) extending between first and second insulative supports and a second portion (25b) extending in a direction normal to the first portion. The second portion includes a first stationary contact (25c) element and a heat radiating surface (25b, 25f) for radiating a substantial amount of heat generated by an arc so that the amount of heat which is conducted to the first support (13) is insufficient to cause a fusion to occur therein. A second stationary contact member (26) has a third, elongated portion (26a) extending between the first and second supports and a fourth, elongated portion (26b) extending in a direction normal to the third portion in spaced relationship to the second portion (25b) and having a second stationary contact element (26c) in opposed relationship with the first stationary contact element. A coiled-core structure is secured between the insulative supports for operating a movable contact member between the first and second stationary contact elements.
