Abstract

Provided is a switch apparatus and a making and usage method thereof. The switch apparatus comprises a switch turn button, a pulling rod, a microswitch, an overflow valve, a pump head, a microswitch box and a housing, wherein the microswitch is fixed on the bottom inner wall of the microswitch box, one end of the overflow valve is connected to the pump head, the other end of the overflow valve isprovided with an overflow valve rod, the switch turn button is connected to a connecting rod at one side in the housing, one end of the pulling rod extends out of the microswitch box and is located at the lower part of the connecting rod of the switch turn button, the other end of the pulling rod is located at the upper side of the contact of the microswitch and the lower side of the overflow valve rod. The invention includes two non-interfering microswitches which are arranged side by side, which can increase the sensitivity of the switch apparatus and improve the reset force of the contact of the microswitch. Besides, the whole switch apparatus can still work if one of the microswitches is broken. Moreover, the switch apparatus is characterized by simple operation and convenient usage.

Description

technical field [0001] The invention relates to a switch device, in particular to a switch device applied to a high-pressure cleaning machine and a method for making and using the switch device. Background technique [0002] The micro switch is a fast switch actuated by pressure, also known as a sensitive switch. Its working principle is: the external mechanical force acts on the action reed through the transmission element (press pin, button, lever, roller, etc.), and after the energy is accumulated to the critical point, an instantaneous action is generated, so that the moving contact at the end of the action reed Quickly connect or disconnect with the fixed contact. When the force on the transmission element is removed, the action reed produces a reverse action force, and when the reverse stroke of the transmission element reaches the action critical point of the reed, the reverse action is completed instantaneously. The action speed of its moving contact has nothing to...
