Micro switch trigger device and micro switch module using the device

Abstract

The invention provides a microswitch trigger device and a microswitch module of using the same. The microswitch trigger device comprises a bracket which is provided with a force transmission part in an oscillating manner, wherein the force transmission part is provided with an avoiding groove; a first contour surface for pressing trigger buttons of microswitches and a second contour surface which is symmetrical about a first symmetrical plane are formed on two groove wall surfaces, close to a groove opening, of the avoiding groove respectively; a rotation axis of the force transmission part is on the first symmetrical plane; the force transmission part also comprises a first contact part in contact with a trigger part and a second contact part which is symmetrical about a second symmetrical plane; the force transmission part is provided with a free position, a first direction trigger position and a second direction trigger position; the second direction trigger position is opposite to the first direction trigger position in direction; and the microswitch device also comprises a reset mechanism for resetting the force transmission part to the free position from the first direction trigger position and the second direction trigger position. By the microswitch trigger device provided by the invention, two-way same position triggering of the microswitches can be achieved; the structure is simple; and the manufacturing cost is low.

Description

technical field [0001] The invention belongs to the technical field of micro switch applications, and in particular relates to a micro switch trigger device and a micro switch module using the device. Background technique [0002] The micro switch is a quick changeover switch actuated by pressure. Because the distance between the contacts of the switch is relatively small, it is called a micro switch, also known as a smart switch. The external mechanical force acts on the action reed through the transmission elements (press pins, buttons, levers, rollers, etc.). Tap to quickly connect or disconnect. When the force on the transmission element is removed, the action spring produces a reverse action force, and when the reverse stroke of the transmission element reaches the critical point of the action of the reed, the reverse action is completed instantaneously. The contact spacing of the micro switch is small, the action stroke is short, the pressing power is small, and the ...
