Contact support supporting mechanism in auxiliary switch

Abstract

The invention discloses a contact support supporting mechanism in an auxiliary switch, which comprises a shell, wherein the shell is internally provided with a contact support arranged in a sliding mode, the contact support is provided with a moving contact, the shell is further internally provided with a static contact, the moving contact moves along with the contact support so as to be abutted against or away from the static contact, the contact support and the shell are provided with a kicking elastic member therebetween in an abutting manner, the kicking elastic member includes a first position which is abutted against the contact support to enable the moving contact to be away from the static contact and a second position which is abutted against the contact support to enable the moving contact to be abutted against the static contact, one end of the kicking elastic member is arranged on the inner wall of the shell in a swinging manner, and the other end is abutted against the side wall of the contact support in a swinging manner. The contact support supporting mechanism is simple in structure, the contact support can be effectively supported, the excitation energy required for state switching is small, the contact support is small in stress, and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of switching devices, in particular to an auxiliary switch structure. Background technique [0002] The auxiliary switch is generally provided with a normally closed contact or a normally open contact. In order to maintain the normally closed or normally open state, a counter force spring is required. At present, the reaction force spring is generally a compression spring, and is set along the movement direction of the contact. The reaction force spring acts on the contact support movement direction, hindering the downward movement of the contact support. The greater the force, the greater the energy of the downward movement of the excited contact support, which will easily lead to inaccurate contact support. At the same time, the force on both ends of the contact support will also easily lead to deformation of the contact support structure. affect the service life of the overall structure.
