[0006] In the existing button-type AC electromagnetic relay, the button design is generally a push-type structure, and the relay contact is converted by pressing or rebounding the button on the top of the shell. For a long time, since the button is set on the top of the shell , resulting in a larger product size, which cannot meet the requirements of small installation height and space

Embodiment Construction
[0021] Such as figure 1 , 2, the present invention includes housing 1, magnetic circuit system, contact system, identification plate 2, button 3 and base part. A button 3 with a seesaw structure is arranged on the top of the housing 1. By moving one end of the button forward or backward, the other end of the button drives the moving reed row of the relay to realize the switching of the relay contacts.
[0022] see Figure 3-5 , a left and right pair of bosses 1.1, 1.2 are provided on the inner surface of the shell, and a groove 1.3, 1.4 is respectively arranged on the opposite inner surface of the two bosses 1.1, 1.2, and the two grooves play a role of rotation support.
[0023] see figure 2 , there is an identification plate 2 at the top button of the shell 1, see Figure 8 , 9, there is at least one clamping boss 2.1-2.8 on the identification plate, and there are no less than clamping bosses and corresponding clamping holes 1.5-1.12 on the shell. After the clamping boss...

Abstract
in particular a low height small-sized high power AC, DC electromagnetic relay with a plurality of contacts by utilizing a press-button arrangement, wherein a seesaw structure press-button mechanism is arranged on the top of the outer casing, one end will move forward and backward through the press-button, the other end of the press-button will drive the moving reed row of the relay, thus realizing the contact conversion. The moving reed lead-out sheets are also linked into lead-out row through the insulation member, and are connected through rivet compression, the press-button is mounted on the side surface of the outer casing, a support rotation shaft is arranged at the center of the press-button.
Description
technical field [0001] The invention relates to an electromagnetic relay, in particular to a low-height, small-sized, high-power, multi-group contact AC and DC electromagnetic relay with a button structure. Background technique [0002] As an electromechanical component, relays are widely used in various electromechanical equipment. Conventional small and high-power multi-group AC and DC electromagnetic relays generally include coils, coil leads, iron cores, yokes, armatures, tension springs, moving spring groups, Moving spring part, static spring, contact, arc breaker, base, shell. Among them, the coil is generally installed vertically, the iron core and the yoke are connected by riveting, the armature is riveted with the moving spring group, and stuck on the yoke, and restored by the tension spring. The height direction of the product is large, and the distance between the coil and the contact The isolation is also low, and the dielectric withstand voltage is not high. Ge...
