Fig. 1 is an exploded view of a micro reset microswitch of the present invention;
fig. 2 is a cross-sectional view of a micro reset micro switch of the present invention;
fig. 3 is a schematic view of a micro reset micro switch of the present invention.
Detailed Description
The present invention will be described in detail with reference to the following specific embodiments.
As shown in fig. 1-3, the micro reset microswitch of the present invention is divided into two types, namely a normally open switch and a normally closed switch.
A normally open switch: including base 1, metal contact 2, metal shrapnel 4 and spacing piece 3, base 1 and metal contact 2, metal shrapnel 4 and spacing piece 3 integrated into one piece inlay the shaping, metal contact 2 and metal shrapnel 4 all have leg portion 5 of an organic whole connection and do not are located 1 both sides of base, metal contact 2 has the contact site 201 of an organic whole connection and exposes 1 top of base, metal shrapnel 4 has the elasticity of an organic whole connection portion 401 of bending and is located the contact site 201 top, have the spacing hook 403 and the elastic contact 402 of an organic whole connection on the elasticity portion of bending 401, elastic contact 402 buckles downwards, base 1 rear is equipped with the spacing piece 3 with spacing hook 403 complex, spacing piece 3 is used for restricting the bending height of elasticity portion 401. The metal elastic sheet 4 and the metal contact sheet 2 are not in any contact in a natural state, and are in a normally open state in a circuit, the elastic bending part 401 of the metal elastic sheet 4 is pressed, and the elastic contact sheet 402 moves downwards to be in contact with the contact part 201, so that the circuit conduction is realized; the elastic bending part 401 of the metal elastic sheet 4 with the lost external force automatically resets.
